WPT test cases fail in Safari 15.6 on macOS 12.5 - https://wpt.fyi/results/css/cssom?label=master&label=experimental&aligned&q=caretpositionfrompoint

Only Firefox seems to pass them so far.

I found that it doesn't return the element within the shadow DOM and looked for a way to get it. There doesn't appear to be one yet.

A shadowRoots parameter was added to the draft: https://github.com/w3c/csswg-drafts/pull/10200
