Summary Unexpected result as paragraph z-index changes depending on CSS scale

Example case: https://jsfiddle.net/mdfs3tb0/ An outer div scales a fixed-size inner div (a 'canvas') which contains some elements positioned with translate(). Scaling past the bounds of the inner div will cause the z-index of the stacking order of the paragraph element to change. This doesn't seem to happen in other browsers and seems unexpected.

I think this is about clipping and the overlap map; I recall another bug that's probably related.
