screenshot of has pseudo-class bug
Congrats on launching the :has() pseudo-class! Excited by all the possibilities this will open for styling.
One unexpected side effect I'm seeing when testing— it appears that `:has()` sometimes matches for non-matching elements. The inspector doesn't show the styles but they appear on-page. If I comment out the styles in the inspector and then un-comment them, they disappear.

This bug is critical to the use of `:has()` so this should be resolved before the `:has()` pseudo-class is released into the production browser.</pre>
