Unless I'm thinking incorrectly, it doesn't preclude parallel layout,
as long as the two viewport elements are at the same level of
"nesting".  Any selectors relying on viewport sizes can only rely on
already-resolved ones, which is a set shared between the two, so they
don't need to interact directly.

Right, I'm less and less sure that this works, unfortunately.  :/
Viewport elements themselves can give nice benefits, but this seems
like it might erase a lot of other speed benefits we'd like to have.
