FF131 adds support for "new shadow dom behaviour" in
Document.caretPositionFromPoint()in https://bugzilla.mozilla.org/show_bug.cgi?id=1914596Essentially this means a new option, called
optionshas been added the the api, along withx,y. The option allows a caller to supply a list of shadow roots, which allows the caret position to be resolved (or not, if not supplied).Chrome implemented this in their first release (128), but FF implemented the API in FF20, so this is a compatibility difference. I've added the option as a method subfeature.
