Shouldn't the screenshots show the opposite? The goal of the issue is setting the alignment to start so that elements are in a row starting from left, progressing to the right taking up only their intrinsic size. The screenshots look like they are using some kind of space-between variant or something.

@mturoci , the left part of the screenshot is the fixed implementation and the "space-between" variant is the old (wrong) one.

Got it. I assumed you are showing the change this PR introduced, hence base = old, compare = new. If it's the opposite, all is good.

LGTM.
