Part 7 - Adjust test expectations.

* `/css/css-align/abspos/stretch-intrinsic-size*`: Some tests still do not pass,
  because it uses `<canvas>` which overrides `nsIFrame::ComputeSize`, skipping
  the invocation of `nsIFrame::ComputeAbsoluteAutoSize`.
* `/css/css-anchor-position/`: Anchor positioning is not yet implemented,
  changes are coincidental.
* `grid-baseline-align-001.html`: Baseline alignment of absolutely-positioned
  grid item should no longer stretch it.
