Documentation style bug
Summary
https://devdocs.io/css/:has#browser_compatibility shows the wrong browser compatibility for Firefox. It shows that the pseudo-selector works in Firefox, but it actually has only partial functionality (due to currently incomplete/buggy implementation) and is gated behind a feature flag. (see MDN screenshot below for reference)
