[wpt] Add tests for aspect-ratio + intrinsic-size calculation.
Browse files Browse the repository at this point in the history 
As above. This adds a series of tests for when we have an element with
an aspect-ratio (via. the aspect-ratio property, or by being a replaced
element of some form.

These tests either test stretching in the block-axis (via.
"align-self: stretch" for example) or by explicity setting the height as
"height: 100%;".

When an element has a block-constraint like this, it should try and
resolve it if possible, then transfer this size in into the inline
direction for the min/max content size.

See: https://drafts.csswg.org/css-sizing-3/#intrinsic-sizes

"Note: When the box has a preferred aspect ratio, size constraints in
 the opposite dimension will transfer through and can affect the auto
 size in the considered one. See CSS2§10."

For example:
<div style="display: flex; width: min-content; height: 100px;">
  <div style="aspect-ratio: 1/1;"></div>
</div>

Here the flexbox ends up being 100x100 as the element with the
aspect-ratio transfers its stretched height (100px) to its width.
