Re: [csswg-drafts] [css2][css-flow][css-sizing] How do min/max block sizes affect bottom margin collapse with last child? (#12218)

And I didn't test that since it's only implemented in Blink, but `calc-size()` also raises some questions.

Let's say a `height: auto` behaving as 100px allows margin collapse. I guess

 - `height: calc-size(auto, size)` and `height: calc-size(auto, 100px)` should still allow margin collapse
 - `height: calc-size(auto, 500px)` should not allow margin collapse despite the `auto` basis, because the margins won't even be overlapping
