This patch doesn't change the visual appearance of the page (since we don't draw anything for resizers on iframes), but is still important for chromium since without it we can get into a situation where a GraphicsLayer is still alive but suddenly vanishes from the layer tree, which our compositor currently isn't robust to. I'll try to address that in parallel as well, but IMO this is a cleaner fix to the problems caused by this inconsistency.

Whoops, I put chromium-generated results in compositing/iframes/, and that layer tree isn't valid for mac snow leopard, which doesn't have layers for scroll corners. I'll fix up the expectations before landing.
