the depth test for stacking items in 3D space is inaccurate - suggesting to remove it for this version.

Comment on attachment 54778 [details] Remove the simplistic depth test OK. Do we have no way to test this using repaint tests?
Actually, now that you mention it, the tests in LayoutTests/compositing/geometry seem to test this, and some of them regressed. This patch is still good - but I probably need a couple of more patches to fix those regressions.
Sorry, my last comment was meant for another bug. There's no way to test this because the depth-test functionality is not specified anywhere. The depth-test functionality is a completely platform-specific choice.
