<!--
content size suggestion is 300px
specified size suggestion is 100px
Chrome 87 and Firefox 84a1 disagree about transferred size suggestion here
(Chrome says undefined. Firefox says 300/150 * 25 = 50. See spec issue
above.) but it doesn't matter: this test asserts that the transferred size
suggestion is ignored, because of this from the spec (capitalization
added):
In general, the content-based minimum size of a flex item is the smaller of
its content size suggestion and its specified size suggestion. However, if
the box has an aspect ratio AND NO specified size, its content-based
minimum size is the smaller of its content size suggestion and its
transferred size suggestion.
So here the content-based minimum size is min(300, 100) = 100.
