chore(deps): bump @lexical/code from 0.49.0 to 0.50.0 in /packages/web

[dependabot]

Bumps @lexical/code from 0.49.0 to 0.50.0.

Release notes

Sourced from @​lexical/code's releases.

v0.50.0 is a monthly release with a large number of PRs to improve correctness, accessibility, and performance. It also ships HMR support, compiled keyboard shortcut dispatch, and screen reader announcements for headings and auto-links, and build-time tree-shaking annotations (in a new @lexical/compiler package). We have upgraded to pnpm 11, so if you're working directly with the monorepo you will need to upgrade as well.

Breaking Changes

• lexical — LexicalNode.replace() no longer re-homes a named slot value. A slot value has no parent (its up-link is __slotHost), so replacing one through the tree API now fails with an actionable invariant instead of a generic parent error; use $setSlot on the owning host. $setBlocksType and the block converters skip slot values for the same reason (#8938, #8905, #8901)
• @lexical/clipboard — The Lexical JSON clipboard payload (application/x-lexical-editor) now asks excludeFromCopy('clone') instead of 'html', matching the destination the rest of that payload already uses. Nodes that opt out of HTML export but expect to survive a clone (e.g. MarkNode) are copied again; custom excludeFromCopy implementations that keyed on 'html' for this channel should be updated (#8995)

Behavior Changes to Watch

These were merged as bug fixes rather than breaking changes, but they change observable output — check them if you snapshot HTML, assert on the DOM, or depend on the old editing behavior.

• HTML export emits a terminating <br>. A trailing LineBreakNode in a block now exports an extra <br data-lexical-managed-linebreak="true">, mirroring what the reconciler already puts in the live DOM, so <p>a<br></p> survives an export/import round trip. Both importers drop the marker, but exported-HTML fixtures will differ (#8765)
• Rich text mounts an aria-live region by default. HeadingAnnounceExtension (via RichTextExtension) and AutoLinkAnnounceExtension (via AutoLinkExtension) depend on AriaLiveRegionExtension, which appends a live-region <div> to document.body — or to the configured owner element. Opt out with configExtension(HeadingAnnounceExtension, {disabled: true}) (#8908, #9071)
• Select-all delete and cut now remove the blocks. A whole-document range is widened to the top-level blocks, so the editor is left on a fresh empty paragraph instead of an emptied heading, quote or list that went on styling the next character typed — and Cmd+X now carries those blocks, so pasting restores them (#8884)
• A formatted paragraph copies as a block. ParagraphNode.extractWithChild now keeps a fully-selected paragraph that carries alignment, indent or inline style in the payload as a block, instead of splicing its children in and dropping that formatting. Paragraphs with none of it serialize as before (#9059)
• importJSON applies registered node replacements. JSON deserialization builds through $create, so a replacement's class is constructed and its importJSON runs; a deprecated replace without withKlass is still applied the old way (#9061, #9090)
• Listener return types tightened. Only RootListener and EditableListener are typed to return a cleanup function; returning one from another listener is now a TypeScript error — it was never called (#8990)
• Collab and Markdown output shifts. @lexical/yjs no longer syncs root textFormat/textStyle (#8940); Markdown import restructures nested mixed-type lists and stores fence metadata in a new mdCodeMeta node state (#8283)
• New invariants. Replacing a slot value (#8938), an insertText anchor that is not a text node, an empty KeyboardShortcutMatch key, and a createBindingV2 getXmlText/getXmlElement that returns an un-integrated or misnamed type (#6483) now throw instead of failing later

Deprecations

• lexical — CAN_UNDO_COMMAND and CAN_REDO_COMMAND are deprecated in favor of the canUndo / canRedo signals on HistoryExtension. A command only reports a change, so a listener registered after initialization can't read the current value; the signal always holds it (#8918)

New APIs & Features

• @lexical/compiler — New package that injects /* @__PURE__ */ annotations and inlines the trivial side-effect-free factories (defineExtension, configExtension, safeCast, createCommand, createState, …) at build time, as a Rollup and Vite plugin. Hand-written annotations on those calls are no longer needed (#9086)
• @lexical/extension — HMRExtension (with HMRConfig, HMROutput, HotContext) keeps an editor alive across hot module replacement. @lexical/react gains LexicalMenuOption, LexicalAutoEmbedPluginUtils, LexicalTypeaheadMenuPluginUtils and LexicalCollaborationContextUtils entry points that split values out of component modules so Fast Refresh works — the original exports are unchanged (#8959)
• lexical / @lexical/extension — Compiled keyboard shortcut dispatch: compileKeyboardShortcuts, CONTROL_OR_ALT, CONTROL_OR_META, CONTROL_OR_OTHER_KEY, keyboardEventMaskForPlatform and the KeyboardShortcut* types in core, plus KeyboardShortcutsExtension and formatKeyboardShortcut for declaring named shortcuts and rendering them per platform (#8876)
• @lexical/rich-text — HeadingAnnounceExtension announces heading changes to screen readers, on by default in RichTextExtension; @lexical/link's AutoLinkAnnounceExtension does the same when typing turns text into a link, on by default with AutoLinkExtension (#8908, #9071)
• @lexical/list — Opt-in WordListImportExtension reconstructs list structure from Microsoft Word HTML (MsoListParagraph classes and mso-list metadata) on paste (#9082)
• @lexical/rich-text — New shouldHandlePasteAsFiles config (and exported defaultShouldHandlePasteAsFiles, plus an optional third argument to registerRichText) lets an app decide that pasted files win over the incidental text/html browsers attach when an image is copied. The default is unchanged: files are handled only when the clipboard carries no text content (#8902, #8699)
• @lexical/yjs — CreateBindingV2Options__EXPERIMENTAL allows a custom Yjs XmlText, so a Lexical document can live inside a larger shared type (#6483)
• lexical — New $getSelectionSlotFrame (#9052) and $flushSyncAfterUpdate (#9067) exports; $isBlockFullySelected moved into core and is still re-exported from @lexical/utils (#9059); @lexical/table now exports the TableCellHeaderState type (#9038); JSDoc added across the core exports (#8895)
• Performance — Bulk inserts and removals no longer walk the parent's children to compute an offset the selection never reads, which made those operations quadratic (#9108)

Notable Fixes

Named slots & the node tree

• Line breaks inside a slot insert and delete correctly (#8899); a managed line break is restored in wrapped slot hosts (#9066); reading the parent style of a slot value no longer throws (#8950); a slot-bearing decorator host is deleted correctly at the selection boundary (#8905)
• replace() keeps the parent's __size correct when handed a sibling (#8917), and splice no longer creates a sibling cycle when it re-inserts a node after the range (#8916)

Node state, copy/paste & serialization

• HTML import/export and slot frames carry the whole node state, keeping the HTML and Lexical clipboard payloads in agreement (#9052); copy and insert keep the original node's state (#9059); list operations and DOM import/export keep the node's own state (#9050); inline node transforms keep the node and its DOM in step (#9060); code blocks keep the caret and their own attributes (#9056); blocks pasted after consecutive line breaks are preserved (#8890)
• Nodes keep their own properties across clone, split and export: EditorState.clone() keeps _parsed (#8989), AutoLinkNode.insertNewAfter keeps its properties (#8996), a split heading keeps its format and style (#8926), split lists continue numbering from the item's value (#8913), and in the playground the Excalidraw drawing and size survive a clone (#8984), a closed collapsible no longer exports as open (#8994), mention nodes keep their display text (#8999), custom nodes keep the theme classes createDOM applied (#9049) and an unparseable data-lexical-datetime no longer breaks serialization (#9047)
