Attempting to rebind the forward and back buttons on a mouse (the 2 side buttons) doesn't work.
STEPS TO REPRODUCE
1. System Settings -> Input Devices -> Mouse -> Re-bind Additional Mouse Buttons -> Add Binding
2. Pressing the two side buttons (buttons 8 and button 9 as shown in xev) doesn't do anything.
Nothing happens, doesn't rebind.
It should allow me to rebind the buttons.
