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.
