I'd like to ask devs when they think :has css selector will be finally fully implemented in firefox. In fact, it's the only browsers blocking this revolution in css authoring.
That's also what I thought when I first heard of the `:has()` selector, but apparently it's the way it is, although they say it's enabled by default in Firefox Developer Edition since a few days. I can't confirm that (I've manually enabled the flag `layout.css.has-selector.enabled` before updating and it's still shown in bold with the revert to default button besides it in about:config) but I hope that it'll roll out within this year and I'm confident that that will actually happen, at least before the end of 2024.
I'm just the manager and messenger. The real work and kudos belong to my team members David and Emilio in getting this done over the past 6–7 months. 🎊
We came across a few regressions and tweaks we needed to get solutions for. Current goal is to have has() by default in x121 now that release freeze is lifted, and to ride the trains (barring any surprises) to release.
