That seems fairly undesirable, actually, though limiting it only to the 
things that have media queries might be better...

And all its HTML parsed (including whatever onload scripts it runs) and 
layout on that completed, right?

This seems like it serializes things a lot...

But also some of the same constraints apply to the toplevel viewport, 
not just subframes (e.g. its dimensions can change based on what the 
browser UI does, etc).  At some point you just accept that the 
dimensions you have are what you have, even if they might change in the 
future.
