Tests: Make Android Browser 4.0-4.3 dimensions tests green

Android Browser disregards td's box-sizing, treating it like it was content-box.
Unlike in IE, offsetHeight shares the same issue so there's no easy way to
workaround the issue without incurring high size penalty. Let's at least check
we get the size as the browser sees it.

Also, fix the nearby support comment syntax.
