Custom "Toggle fullscreen mode" shortcut broken

[Ipsod]

Ubuntu 16.04 and 14.04 do not recognize custom keyboard shortcut for Toggle fullscreen mode.

Other custom shortcuts, like Toggle maximization state, are working properly.

I've tried many different settings for Toggle fullscreen mode in keyboard settings, including ctrl+alt+o, super+8, and many others.

To test:

    go to Settings/Keyboard/Shortcuts/Windows
    set Toggle fullscreen mode to ctrl+alt+o (or anything else)
    test whether the shortcut actually works on FireFox (or any other program).

Last tested in Ubuntu 16.04.1 (updated today)

Status changed to 'Confirmed' because the bug affects multiple users.

Is it possible to map one key to another one to circumvent this? For instance, mapping a volume key to F11 might be a helpful workaround for tablet and convertible users.
