Re: [csswg-drafts] [cssom] `ComputedStyleObserver` to observe changes in elements' computed styles (#8982)

What's missing from this for me, and what I thought this proposal actually did, is to observe the elements that _have_ a particular custom property applied, or have a particular value applied to a particular custom property. That would allow other changes, but ultimately, what would be even better [is the ability to create JavaScript worklets](https://github.com/w3c/css-houdini-drafts/issues/1088) so you don't have to "observe" at all, but can run a worklet every time that property is calculated.
