What (even if obvious to you) is the use case, i.e. what operation that 
is commonly needed (maybe also wanted) and must be done browser side 
does this make possible which isn't reasonably possible already?

What happens before a forward reference is resolved?

What happens if a forward reference is never resolved?

What if there is a chain of references?

What happens if such a chain proves circular?

If you really meant relative, which element has its height determined by 
  the selected element, and how are height changes handled?

What is the performance impact of dynamically changing a style sheet 
such that the reference point changes?

These and similar questions really need to be considered in any feature 
request.

Note that, although features that break incremental rendering are being 
added, such features need to be given more consideration than features 
that can be rendered in one pass, as fixing up the display, or stalling 
rendering, are annoying to users.
