<p>Min-height should make the multicol container taller if min-height is greater than the content
    height, but it should not affect column balancing. We specify column-fill:auto here, but the
    columns should still be balanced, because height is auto. Note that in this test, the balanced
    content is shorter than min-height, which is what matters. The height of the uncolumnized
    content (i.e. the flowthread), on the other hand, is actually greater than min-height (but that
    shouldn't make any difference).</p>
<p>Below there should be a blue square above a yellow square.</p>
