Fix a bug with comment box positioning.

Browse Source 
Summary: We do want to only apply updates when a view previously wasn't mounted and didn't have a backing view created.  Previously we were applying updates to the view regardless of the mount state, which resulted in positioning bugs.  Rather than revert, I cleaned up the code Ahmed fixed, since didUpdate || ensureBackingViewIsCreated() was both a bug and obscure, as the two should have a swapped order.
