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

I think the concern was that in [this testcase](https://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E%0A%3Cstyle%3E%0Adiv%20%7B%20width%3A%2050px%3B%20height%3A%2050px%3B%20margin%3A%202px%3B%20%7D%0A%3C%2Fstyle%3E%0A%3Cdiv%20style%3D%22transform%3A%20rotateY(180deg)%3B%20backface-visibility%3A%20hidden%3B%20transform-style%3A%20preserve-3d%22%3E%0A%20%20%3Cdiv%20style%3D%22transform%3A%20translateX(0)%3B%20will-change%3A%20transform%3B%20background%3A%20green%22%3E%3C%2Fdiv%3E%0A%3C%2Fdiv%3E) the green rectangle is interoperably shown and we were hesitant to change that, at least in the same change that's needed to fix the Interop2023 failure.  (That said, in Chrome it's shown because of the `will-change: transform` on the inner div, in Safari because of the `transform` on the inner div, and in Firefox because of either.)
