+<p>Trigger layout inside a clipped box inside a multicol container that has a spanner. Then trigger |
+ layout outside the clipped box, but still inside the multicol container. This 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 a blue square below, and nothing else (no red, no "FAIL").</p> |
