  The containing block (.container) is 50px tall. The abs-pos element has
  height: fit-content. Its child has height: 100%, which should resolve as
  indefinite (auto) since the parent has an intrinsic height. The child then
  sizes to its content (100px), making the abs-pos element 100px tall.

  If the bug exists, height: 100% resolves against the containing block (50px),
  making the abs-pos element only 50px, exposing 50px of red below.
