1003780 - New menu lacks overflow hidden when all items are removed

Status: RESOLVED DUPLICATE of bug 996121

(Firefox :: General, defect)

Description

[Archil Imnadze]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140421221237

Steps to reproduce:

Install Firefox 29.
Remove all items from the new menu (you should see an animal sliding).
Wait for the animal to touch the bottom of the available area.


Actual results:

Vertical scroll bar flickers. But as soon as the animals starts going upward the scroll bar hides.


Expected results:

The scroll bar should have never been shown. "overflow: hidden" should have been added.

WFM on Fx29 (20140421221237) and 30 for Windows, the vertical scroll always show when lack of available space, and if enough the scroll bar is not displayed.

I don't know how to take a screenshot of this situation. The scroll bar hides in less than a second.

My assumption is that the container element has a 'display: inline-block' and lacks 'vertical-align: top'. And depending on the system font there can been extra 2-3 pixels on top of it. And this might be causing the overflow below. Could somebody check this and prove me wrong?

This seems like the same bug as bug 996121. Can you share more details about the system you are running and what is the default font and font-size?
