We should also resolve what happens when the author specifies transform-style:preserve-3d, but a grouping property forces it to flat. Consider a testcase that has a preserve-3d element, and then you later add a grouping property that doesn't force a stacking context and containing block (overflow:hidden, clip, clip-path etc). I find it a bit weird from an implementation standpoint that the change handling for overflow:hidden (which normally has nothing to do with containing blocks) needs to check if we also have transform-style:preserve-3d, and disable us from being a containing block. It's a weird dependency. I think authors might also find it weird that adding a grouping property not only changes the visual rendering of preserve-3d, but also has the layout change of removing the containing block. I'd prefer if the flattening effect of grouping properties applied to the rendering model, but not the layout. We could spec that as defining the stacking context/containing block parts of transform-style:preserve-3d are determined by the computed value of transform-style. -- GitHub Notification of comment by mattwoodrow Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/1950#issuecomment-342619182 using your GitHub account
