(Core :: Layout, defect)

Another Flexible Box Layout bug. Refer to
http://oli.jp/bugs/mozilla/flexbox-overflow.html
for example.


Reproducible: Always

Actual Results:  
When flexbox children are too wide for the box element’s declared width, FF ignores the width and expands the child and box element to contain the content.

Expected Results:  
WebKit allows content too wide for the box element’s child to overflow out of the box element.

The example boxes should be 400px wide, the same as the blue box.

Just FYI this is regarding OLD Flexbox (display: box;), not NEW Flexbox (display: flex;), and the chances of it being fixed are probably not great. For more background:
