closed root shadow dom support proposal

[pavelfeldman]

Codemirror5 currently does not work in a closed shadow root. A fix like this would make it work. Would you be interested in a PR? getRootNode() exists in all modern browsers for years now, not sure how much of a compatibility impact it is for cm5 deployment.

CodeMirror also targets old browsers, so this would have to be wrapped in a helper function with a fallback.

Also, did you test on Safari? That browser still has rather broken selection management in shadow DOM.

Sounds good

I did not, but I will.

I'll read it as a potential interest.
