Some keyboard shortcuts with <Super> key don't work

### What Happened?

I remapped these keyboard shortcuts:
- `Applications`->`Launch nth dock item`: disabled (all) to free the key mappings
- `Workspaces`->`Switch to workspace n`: `Super n` (i.e. ` Super 1`, `Super 2`, etc.)
- `Workspaces`->`Move to workspace n`: `Super Shift n` (i.e. ` Super Shift 1`, `Super Shift 2`, etc.)

In general they work but some of them don't:
- ` Super 7`
- ` Super Shift 4`, ` Super Shift 8`, ` Super Shift 9`

When having an app window focused which accepts text input (e.g. the Terminal) then (instead of triggering the configured action) the corresponding key combo without `Super` gets sent to the app window, i.e. in the example above (with my German keyboard layout) `7`, `$`, `(`, `)`.

Note: Maybe related to my German keyboard layout, compare https://github.com/elementary/settings-keyboard/issues/559.

### Steps to Reproduce

1. Remap keyboard shortcuts as mentioned above (don't know if this is mandatory).
2. Create 8 workspaces by placing some app window on each.
3. Open a Terminal on workspace 1 and have it focused.
4. Try all keyboard shortcuts `Super 1` - `Super 8`/ `Super Shift 1` - `Super Shift 8`.

### Expected Behavior

Keyboard shortcuts should work as expected.
