[csswg-drafts] [css-values-4] Logical viewport units (vi, vb, etc) and writing-mode propagation (#6873)

andruud has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-values-4] Logical viewport units (vi, vb, etc) and writing-mode propagation ==
> [<lvi, svi, etc> are] equal to 1% of the size of the large viewport size, small viewport size, and dynamic viewport size (respectively) in the direction of the **root element’s inline axis**.

If writing-mode is propagated from body to the viewport, are these units supposed to resolve according to the propagated writing-mode (e.g. if used on e.g. the root element)? At the time we know what to propagate from body, it's too late to change any interpretation of *i,*b on root.

Can we specify that these units resolve against the _computed value_ of writing-mode on the root element? This is what WebKit did in their implementation.
