when one uses hz and/or protrusion. I don't know why folks expect
expansion and protrusion to give better (or intended) output when the
other constraints are such that tex either not even ends up in the phase
where expansion is applied, or when fitting the constraints is only

will not get better. Read: expansion is a last resort in getting things

Anyway, with tolerant and stretch the test looks ok here.
