Oriol Brufau d5c55eb87c layout: Fix bottom margin of block-in-inline getting ignored (#42889) ...

In order to know whether a block box can collapse its bottom margin with
the bottom margin of its last child, we need to check its tentative
block size. Most usually, this will be the block size of the containing
block that is used when laying out the children.

However, anonymous blocks do not establish a containing block. So using
the containing block for children meant that we were using the tentative
block size of its parent. If that parent had a definite size, this would
prevent the anonymous block from collapsing bottom margins with its
children. This situation could happen when placing a block-level inside
of an inline box.

This patch fixes the problem by using an indefinite tentative block size
for anonymous blocks, instead of the containing block for children.

Testing: Adding new test
Fixes: #42469
