import MatDatepickerModule with "Redux DevTools" chrome extension causes an error and app crash.

Bug, feature request, or proposal:

Importing MatDatepickerModule when using ngrx StoreDevTools with "Redux DevTools" chrome extension causes an error.

Very similar behavior to what is described here: ngrx/platform#61

What is the expected behavior?

No error && crash.

What is the current behavior?

What are the steps to reproduce?

• import MatDatepickerModule
• import StoreDevtoolsModule (from ngrx/store-devtools)
• "Redux DevTools" chrome extension

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

"@angular/common": "^5.2.0",
"@angular/material": "^5.1.1",
"typescript": "~2.5.3",

OS: OSX
Browser: Chrome Version 63.0.3239.132

Is there anything else we should know?

Check discussion here: ngrx/platform#61

Error goes away if you remove/disable a single of the following:

• imports: [ MatDatepickerModule]
• imports: [StoreDevtoolsModule]
• "Redux DevTools" chrome extension
• polyfill: import 'core-js/es6/date';

[jelbourn]

Are you saying this only happens with a certain Chrome extension enabled?

@jelbourn yes, its an extension to debug Redux actions, so it has some interaction with ngrx's StoreDevtoolsModule which, as described, also needs to be imported to trigger this error.

[jelbourn]

If things work without the extension and then break with the extension, I'd say the issue is probably in the extension and out of the scope of Angular Material.
