| 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. |
