When commenting out a tag in HTML, CodeMirror wraps it in `/*` and `*/` instead of HTML Comments `<!--` and `-->`. I assume the language detection is trying to comment within the script, but doesn’t take into account the cursor/highlighting position that’s still in the HTML context.

Noting that this also happens with `<style>` tags

That was a recent regression in @lezer/common. This patch should fix it.
