It was mentioned before that you have a util to check if the DOM can be used. I don't think this check is being used in the LexicalTypeaheadMenuPlugin, considering I'm getting
this error:

ReferenceError: document is not defined
    at useMenuAnchorRef (....../node_modules/@lexical/react/LexicalTypeaheadMenuPlugin.dev.mjs:337:74)
    at LexicalTypeaheadMenuPlugin (....../node_modules/@lexical/react/LexicalTypeaheadMenuPlugin.dev.mjs:534:28)

I'm running a remix project and trying to import the playground. I ran into all sorts of problems, so I used React.lazy to import the component only in the frontend. That solved all of the issues, however the above error is logged during server rendering.
