-layer at (8,8) size 320x240 +layer at (8,8) size 320x240 scrollHeight 265 Antoine, Simon, does this means that scrolling occurred? I don't see anything in the test that would perform scrolling. Could it be a preceding test leaking a UI side action? -layer at (8,8) size 320x14 +layer at (8,8) size 320x50 And all of these are different height - what does that imply?

I don't think that means it's scrolled; it just overflow:scroll and that's how big the content is. > -layer at (8,8) size 320x14 > +layer at (8,8) size 320x50 > > And all of these are different height - what does that imply? No idea. Maybe media people can say.
