Re: [csswg-drafts] [css-contain-3][css-animations][css-transitions] Isolate animation side-effects? (#6398)

Overall this sounds great! I'm glad that we can behavior that makes sense to developers

How are container units defined? I would have thought that they would be similar to percentages, viewport units or calc where the computed value is a calc that does not itself change when the input variables change. Unfortunately, I can see that this is not the case at least for vw from the [demo](https://output.jsbin.com/gunuvem) I put together to test this. It seems there is plenty of precedent for it starting transitions.
