Re: [csswg-drafts] [css-values-4] Add vhc value (#4329)

`vh` doesn't pay attention to scrollbars, so that it can be a computed-value time unit and not depend on layout.

But nothing stops `vh` from responding to UA chrome hiding/showing. That's not a content-based decision, it just happens as a result of user interaction. It means we have to invalidate as the chrome disappears, but otherwise is not problematic. I think we can just clarify that the viewport units should do so.
