Let's see. Consider this pseudo-markup:

  <div class=height-constrained-multicol>.... <img class=tall> ....</div>

Are you saying that the height of the column boxes will depend on the
value of the 'column-fill'? So that, 'column-fill: balance' makes them
taller than the multicol box and 'column-fill: auto' makes them as
tall as the multicol box?

That doesn't make much sense to me, so you must be thinking of
something else :)

Yes. But the background color, if set on the multicol element, will
also disappear.
