In OnShellOnNavigated, when e.Current?.Location is null and EnableAutoTransactions is true, the method returns early at line 584 without calling FinishNavigationSpan(). However, OnShellOnNavigating would have already started a navigation span via StartNavigationSpan(). This leaves the span in an unfinished state, causing a resource leak where the span remains open until some other event (like another navigation, window stop, or button click) happens to close it.

When UseHub is called with a HubAdapter, the code attempts to log an error via hub.GetSentryOptions()?.LogError(...). However, GetSentryOptions() on HubAdapter delegates to SentrySdk.CurrentOptions, which calls CurrentHub.GetSentryOptions(). At this point, CurrentHub is still DisabledHub.Instance (or the previous hub), and DisabledHub returns null for GetSentryOptions(). This means the error message will never be logged, making the diagnostic message dead code.

The test method name was changed from Window_PopCanceled_AddsBreadcrumb to Window_PopCanceled__AddsBreadcrumb, introducing a double underscore (__) which is inconsistent with all other test methods in the file that use single underscores as separators. This is likely an accidental typo rather than an intentional change.
