Title: Elements without style causing runtime error in SC 2.2.2

Fix issues raised by certain sites that have unusual frames, to the point where this Success Criterion's tests for blinking elements was failing due to a complete lack of computed style. This failure only occurred in Firefox.

A common example was sites using Twitter's provided "Tweet button", which was creating a hidden, sourceless inline frame (interpreted as about:blank by browsers), and this was causing this test to trip on its html element.
