Summary <canvas> contents render on top of overlapping <div> even when they shouldn't

Non-positioned elements that overlap (e.g. by using negative margins) should be painted in DOM order - and this happens for "regular" elements. However, <canvas> elements that should render below an overlapping <div> actually render their contents on top of said <div> See attached files for sample with both 2D and 3D <canvas>es.
