In such a case, we compute an incorrect intrinsic logical height, because
we resolve pre-flex percentages when we calculate the intrinsic height.
In common cases this can be 100% of the flexbox height, which we later
use as a min-height of the flex item, leading to it not shrinking when
it should.

This reverts https://crrev.com/c/1269235 for the case of a flex item
which is a flexbox with percentage children.
