REGRESSION (r191499): Tab content "jumps" down when focusing tabs that load in the background

It should be possible to write an API test that ensures that top content inset/view state changes are deferred until endDeferringViewInWindowChanges. Will try that at some point.

That's what the comment above yours is about. I'm going to land this, but also make a test because I think it should be straightforward.
