> trchen, I don't really understand what problem this patch is solving.  Is this just a stylistic improvement, or is there a concrete benefit from this patch?

Working on the render tree should not trigger layout behavior, otherwise the tree can mutate while we're still traversing on it. This fixes a crash we have in downstream.
