1220386 - Inconsistent hit testing close behavior and transition-less effect on Hamburger Menu

Status: UNCONFIRMED

(Firefox :: Menus, defect)

Description

[bull500]

Transition Effect:
On Windows Firefox hamburger menu has a smooth fade in effect.  
That is visibly omitted on the Linux version and it just pops-up like any ordinary menu.  
GTK3 does provide menu transition effects and possibly this could be used in the GTK3 Firefox versions.  

Inconsistent behavior:
Open the menu and closing it can be done by normally clicking on the Hamburger Menu icon but there appears to be an inconsistent behavior. 
It only closes if you click within the '3 lines image icon' and not within the boundary region(left or right of those 3 lines) of the button.  

Hence the menu flashes when you try to close it by clicking the Hamburger menu button if you click a bit away from the '3 lines' image.
This does not occur on Windows version and you can click away from the 3 lines within the menu button and it works flawless.  
This also affects the Firefox Hello button.   

FF 45.0a1 (2015-10-31); Fedora 22

Not a regression from GTK 2 -> 3 transition.
