<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>

<!--
  1st: A green rect 50x100.
       border-left is 10x100 and the content box is 40x100.
       We use 'aspect-ratio: auto && <ratio>', so the aspect-ratio works with
       content-box dimensions always. The inline size of the content box is
       (50px - 10px) = 40px, so the block size is 40px * 5/2 = 100px.
       (note: width here is the inline size of border-box.)

  2st: A green rect 25x100.
       border-left is 15x100 and the content box is 10x100.
       (note: width here is the inline size of content-box.)

  3nd: A green rect 25x100.
       border-left is 15x100 and the content box is 10x100 because we compute
       the block size by aspect-ratio which works with border-box and so the
       block size is 25px * 4 = 100.
       (note: width here is the inline size of border-box.)
