Here are the modification to those reftests in our reftest framework. In these
sub-tests, the grid containers' widths become the same as their items' width,
and Firefox now has the same behavior as Google Chrome.
- `grid-auto-min-sizing-min-content-min-size-002-ref.html`: test 7, 8, and 9.
- `grid-auto-min-sizing-min-content-min-size-004-ref.html`: test 4 and 6.
- `grid-auto-min-sizing-transferred-size-002-ref.html`: test 8, 12, and 13.
- `grid-auto-min-sizing-transferred-size-004-ref.html`: test 4 and 6.
- `grid-min-content-min-sizing-transferred-size-002-ref.html`: test 8, 12, and 13.
- `grid-min-content-min-sizing-transferred-size-004-ref.html`: test 4 and 6.
Note: `grid-auto-min-sizing-transferred-size-002.html` is marked as `fails`, and
this patch just change those sub-tests that have behavior change introduced by
this bug.
