Comment 7 for bug 1261369

After some more testing, I found unfortunately there is a problem with the patch and I will need to revert it.

When the menubar is hidden, shortcuts with the Alt modifier (like Alt + Left, Alt + Right) will perform their action correctly but toggle the menubar too, and it is not simple to prevent this, ruining the experience for users that like the menubar hidden. Changes in various places would be required to accomplish this, which makes it more complicated. I will think about a proper solution later.
