| <p>Add a spanner inside a fixed-size clipped block inside a multicol container. It should not be |
| affected by the clipping, since the containing block of a spanner is the multicol |
| container. This also tests that we don't perform any optimized subtree layout operations |
| incompatible with multicol (which would typically cause assertion failures).</p> |
| <p>You should see the word "PASS" below, and nothing else (no red, no "FAIL").</p> |
