Re: [csswg-drafts] [css-sizing] `height: stretch` should just behave as `height: auto` (#1614)

As we were drafting text for this resolution, @tabatkins and I noticed that we had discussed what to do in cases where 'align-self: stretch' applies, but not so much where it doesn't.

Our [current draft]( includes a paragraph defining these cases (where there's no 'align-self: stretch' behavior to hook into, such as the height of block boxes) to match the behavior of '100%', modified to apply to the margin box to effect the desired "fill container" behavior. (This specs the behavior suggested in the earlier )

In cases where even percentages can't resolve, it falls back to auto.

This new text still avoids the "blow up all the elements up to the nearest definite-height ancestor" behavior that was previously there, which inspired this issue in the first place; instead, it only references the nearest containing block, same as percentage resolution. And while it can still cause overflow in a container with a height:stretch element along with other children, this is no different than 'width: 100%'.
