Part 2 - Mark a flex item's intrinsic inline size dirty if we override its block size.
In a column-oriented flex container, if a flex item's intrinsic inline size or
its descendants' inline size contributions depend on the item's block size,
NS_FRAME_DESCENDANT_INTRINSIC_ISIZE_DEPENDS_ON_BSIZE will be set. In this
case, when determining the flex item's cross-size, we need to mark the flex
item's intrinsic inline size as dirty such that its (auto) inline size is
recomputed when constructing its ReflowInput.

is the test coverage for this patch.
