I would like to be able to instantiate a lexical editor bound to an element within a Shadow DOM. When lexical is configured in this way it fails to properly process updates to that element's contents. I believe that the project has a huge opportunity here, maybe even something like a <lexical-composer> custom element, bringing the vanilla DX closer to React's.

I am happy to implement my own editor as a user as well of course, but that requires a fix for processing updates to the editor element contents in a ShadowRoot.
