1078431 - flex item shrinks below minimum content size

Status: RESOLVED DUPLICATE of bug 984711

(Core :: Layout, defect)

Description

[Michael Hohner]

Attachment: Test case

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0
Build ID: 20140923175406

Steps to reproduce:

The W3C spec says:

"By default, flex items won’t shrink below their minimum content size (the length of the longest word or fixed-size element)."

But this is not the case with Firefox. The flex item can shrink below the minimum content size even when no overriding "min-width" property is specified.

See attached test case. Make the window narrow enough, and the content of the flex items will overlap.

This was a relatively recent spec-change. I added this feature[1] in bug 984711. It looks like that's scheduled to ship in Firefox 34. I'm duping this to that bug.

In the meantime, you can test a current Aurora build if you want to give it a try.

[1] (Added this feature *again*, really -- it was in the spec, and then it was removed, and then added back maybe a year later.)
