1041019 - For flex item with intrinsic aspect ratio, cross size is set based on "flex-basis" instead of on final main size

Status: VERIFIED DUPLICATE of bug 1030952

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert]]

Attachment: testcase 1

STR:
 1. Load testcase.

EXPECTED RESULTS: Purple areas should be square (I think).

ACTUAL RESULTS: Top two ones are tall-and-skinny; bottom is short-and-fat.


In each case, there is a particular "flex-basis" value in play, but we end up at a different main-size (width) from that flex-basis. (because of shrinking in the first two cases, and growing in the last case)

Despite that shrinking/growing, we appear to be setting the flex item's height based on the flex-basis (instead of the final width), combined with the intrinsic aspect ratio.

Actually, this is effectively a dupe of bug 1030952 (see spec quote in bug 1030952 comment 8 in particular).

I verified that this bug's testcase renders as 3 squares now in latest Nightly 49.0a1 (2016-05-02) (which has the duplicate-target bug's fix).
