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.
Also check example #'s at this URL (https://codepen.io/brandonmcconnell/pen/a93e58403165e721481e7fc4fe3fb676?editors=1100):
* Example 6
* Example 7
* Example 8
Each shows certain matched squares that should not be matched. If you inspect those blocks in the inspector, you will see they are not actually receiving the styles but show them visually anyway.
On Twitter I saw a demo pass by that showed the same faulty behavior: https://codepen.io/ZoranJambor/pen/GRMyzvy
Both `<a>` elements get styled, even though the 2nd `<a>` element does not contain a `<span>`.
Fixed in trunk.
