Keybindings with shift + number keys doesn't work

[HarukaMa]

Expected behaviour

Should be able to use keyboard shortkeys with Shift and number keys.

Actual behaviour

If I try to add Shift+1, it becomes Shift+! (<Shift>exclam in dconf) and I can't trigger the action with the key combination. It also doesn't work if I manually change it to Shift+1 via dconf.

Steps to reproduce the behaviour

Try to add any shortcut with Shift and number keys.
