Extra shout-out to @jaffathecake as well, for suggesting “some of the discrete value animation stuff” could possibly be used …

Winging back to the Chrome bug I mentioned, here’s the issue: `allow-discrete` erroneously does not work on custom properties – issues.chromium.org/issues/360

There technically is a workaround for it (by animating `content`) but I haven’t been able to consistently make it work.

Gonna see who I can poke internally to get the ball rolling on it ;)

UPDATE: Jake found a workaround to bypass that Chrome bug: register the custom property with @​property.

That works.

But

…

Safari doesn’t like it. It seems to be stuck in a transition loop when the custom props is registered to contain string values ("<string>" or "*") 😕

Here’s something nice by @matthewp built on top of all this: a Selector Matcher Observer powered by CSSStyleObserver.

When the element matches the given selector, a custom property gets flipped, triggering the callback attached to the CSSStyleObserver.

Yesterday I collected all bugs I could find related to `transition-behavior: allow-discrete` onto a dedicated repo/site [^1] and also filed a bunch bugs.

The WebKit team at Apple didn’t waste any time and moved really fast on this one, as the PR to fix the WebKit bugs [^2] is already merged in! 🤩👏
