Description

[Nicola Ferralis]

Attachment: menu.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150812163655

Steps to reproduce:

Push the menu button once (Hamburger button on top right)


Actual results:

The button appear as pushed (see fig. attached). However no menu is displayed. 
If the button is pushed again, the menu appears. This is very consistent. Essentially, you have to push the menu button twice to open it.


Expected results:

The menu should open at the first and only push of the menu button
