Hi Lexical team, I'm making some changes to the LexicalTypeaheadMenuPlugin such that when we're using the ContentEditable in an iframe but rendering the dropdown menu of the typeahead outside (iframe's parent), we'll still calculate the position of the dropdown menu correctly.

Unrelated to this PR, but maybe we should add editor.getWindow() / editor.getDocument() with fallback to globals. It might simplify swapping globals with jsdom (e.g., for server rendering)

I think, this is a great idea.

@lestertay @fantactuka - I wonder if editor._window should always be set to avoid the fallback to the ?? window in getDefaultView that powers this setter https://github.com/facebookexternal/Outline//blob/02f01f160e8894f133e076ab5e38e7a3fd6a5f7a/packages/lexical/src/LexicalEditor.ts#L961-L967

@fantactuka i think that'll be useful and a sensible fallback. I'll be happy to make another PR to enable this since i've seen quite a few places within Lexical using editor._window.
