### Expected Behavior

Focus should be visible properly on 'Shortcut' edit field. Focus indicator should be provided as outline for better visibility.

### Actual Behavior

'Inline' focus is provided for 'Shortcut' edit field, due to this user is unable to recognize that edit field is focused when focus is on 'Shortcut' edit field.

Reproduce the issue from Settings > Actions by opening an action's Shortcut edit field and navigating with the keyboard. Inspect the focus styling for that field; done means the focused control has a clearly visible outline and satisfies the referenced WCAG focus-visible expectation.
