+<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>
