This patch caused some changes in some other tests. 

I decided to rewrite frame-with-title.html to be more modern and precise.

+	  shouldBe("obj.isAttributeSupported('AXLoadingProgress')", "true");

I'm surprised that AX exposes this sort of data!
 AXLayoutCount: 2
+AXLoadingProgress: 1
At least the "layout count" is shocking. :)

Yea, users want to be able to know the percentage of load completion for webpages. Visually you can see that, but if you're just listening for when the page completely loads, it can be frustrating not knowing the progress

AXLayoutCount is a way to allow the screen reader to have a clue for when the page might have changed enough to invalidate what it knows about the elements on the page. There might be a better way. It was invented years back to get VoiceOver working well.
