Auto merge of #8322 - mrobinson:iframe-resizing, r=pcwalton
Properly resize iframe root layers When a layer containing an iframe changes, we also need to resize the root layer of the subpage. This ensures that content from the child layer tree is masked to the new size. Fixes #8301. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/servo/servo/8322) <!-- Reviewable:end -->
