Being less familiar with the rendering paths, is this something we're going to
need to handle for mirrored roots eventually? I feel like there are a lot of
locations that depend on a top-level FrameView, and I'm not sure we have a good
story for them yet.

I'll leave that for Ken to give input on.

Most of the places that access the top-level FrameView can be changed to instead
access the FrameView of the local Frame root (i.e. root of a connected subtree
of LocalFrames). For rendering that is typically going to be the case, anyway.
Certainly that is the case here, where the FrameView is being used to start a
layout.

I expect there to be exceptions but we can deal with those as we find them.

You can use WebFrame::fromFrame now, so you don't have to do this awkward check
(since the awkwardness is now centralized =)

Yay! ?!
