Automatic update from web-platform-tests layout: Let `stretch` on flex item cross size stretch to the line We were instead stretching to the containing block, which implied that the behaviors of a `stretch` size and `stretch` alignment weren't consistent. As resolved by the CSSWG, the behavior will now be: - If the cross size of the line is known, stretch to the line. - Otherwise, stretch to the containing block. This aligns us with Blink, which has already shipped this new behavior. Signed-off-by: Oriol Brufau <obrufau@igalia.com> -- wpt-commits: 146144f19e30bb5282a25360c69cf8b88a0da220 wpt-pr: 54203

#item has `align-self: start`, which sizes it as `fit-content`.
|
|
Therefore, we initially shrink-to-fit it into the container (100px),
|
|
thus getting a cross size of 100px and a main size of 200px.
|
|
However, we have another item which is 200px wide, so the flex line
|
|
grows to that size.
|
|
Once we know the final cross size of the line, we shrink-to-fit #item
|
|
into the line (200px), thus getting a final cross size of 200px.
|
|
Now both floats fit side by side into these 200px, so vertically they
|
|
only need 100px, but the main size of #item remains as 200px.
