Comment on attachment 71507 [details] Patch Couldn't you make the manual test show success or failure? You're just printing the layerTree into a <pre>, but you could actually look at the text to say "PASS" or "FAIL".

You're just printing the layerTree into a <pre>, but you could actually look at the text to say "PASS" or "FAIL". Remember this is not a layout test. There's no way for me to know if the image is showing up. I can't do layerAsText() unless I'm in DRT and the bug doesn't happen there. So I don't know of any way short of visual inspection to determine if the bug is fixed.

DRT doesn't have the back/forward cache enabled. Maybe that's the problem?

Maybe these days we have a way to enable it for certain tests?
