Re: [csswg-drafts] [css-transforms-2] Preserve-3d + backface visibility semantics need to be clarified (#918)

One issue that came up in [crbug.com/391504029](https://issues.chromium.org/391504029) is whether `backface-visibility: hidden` on an ancestor should inherit to an element that establishes a new 3D rendering context (by specifying `transform-style: preserve-3d` when its parent did not) but does not actually have a 3D transform.  The Chromium code isn't set up to handle this case correctly, so I think at least for now we're going to change it so that this case doesn't apply the `hidden` from the ancestor.

It's not clear to me right now whether or not that makes sense.  (I should probably try to think about it more when I have a chunk of time to load this stuff into my head again...)  But I'd welcome opinions form others on this case.
