Comment 1

[Daniel Holbert [:dholbert]]

(This spec text changed a bit more today, so that now both the min- and max-cross-size are relevant.)

Attachment: testcase 1 (should be 50px wide)

Comment 4

[Daniel Holbert [:dholbert]]

Related issue here -- if the min-content size of an image (or anything with an intrinsic aspect ratio) is smaller than the transferred size, we should be honoring the min-content size, since the flexbox spec says to use the minimum of the two.  (This is a change with respect to the spec text in bug 1015474 comment 0.)

Attachment: testcase 2

(Here's a testcase for the issue in comment 4. Edge gets this correct; Firefox & Chrome do not.)

After bug 1316534, both testcase 1 & 2 are rendered correctly. Tested on Firefox 83.0a1 (2020-09-23).
