In touch-action-none-on-iframe.html we go to paint the RenderWidget, but it has no event-region painting code so we fail to account for the touch-action:none.

This test fails.

I actually believe this might be correct, at the very least the spec is not clear on this topic and Chrome does not prevent scrolling when setting "touch-action: none" on an <iframe> element. I filed bug 213846 to update the test and will raise a spec issue as well to clarify this.
