Bug Description

When setting a new keybinding, if the user navigates back using the back button in the top-left corner and then opens the Shortcuts view again, the shortcut option remains in the input-waiting state instead of displaying the list of shortcuts.

The keybinding input state is not dismissed when navigating back, causing the previous shortcut action to remain active when returning to the Shortcuts view.

Steps to Reproduce

1. Navigate to Keyboard shortcuts
2. Click on a shortcut to get into edit mode
3. Navigate to previous page using back arrow (top-left)
4. Navigate to Keyboard shortcuts again

Expected Behavior

Pressing the back button should dismiss the active keybinding input state. When the user returns to the Shortcuts view, all shortcuts should be displayed normally.
