1147532 - Flex item with aspect ratio & "max-width" still renders with native height

Status: VERIFIED DUPLICATE of bug 1030952

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert] (vacation until Jun 23)]

Attachment: testcase 1

STR: Load attached testcase.

EXPECTED RESULTS: Image renders, scaled down naturally to a (small) wider-than-tall rectangular area.

ACTUAL RESULTS: Image renders, squashed, to a taller-than-wide rectangular area.


NOTES:
* The image's native resolution is 400px wide & 200px tall.
* The image's width is horizontally constrained via "max-width: 150px".
* The image's height isn't directly constrained.

Chrome & Opera 12.16 (Presto) give EXPECTED RESULTS. Firefox Nightly gives ACTUAL RESULTS.

I'm filing this for a bug that was emailed to me - I'm not 100% sure what the spec requires of this scenario yet, but I'm pretty sure our rendering is wrong.

Pretty sure this is a dupe of bug 1030952, actually.  A quick check in GDB shows that the problem described in bug 1030952 comment 2 is still happening here.

I verified that this bug's testcase produces EXPECTED RESULTS in latest Nightly 49.0a1 (2016-05-02) (which has the duplicate-target bug's fix).
