Polish Edit Action page

- Fix key bindings section being hidden when no keys are present
- Fix action name not updating when type changes
- Polish interactions with action type suggestions list
  - select all text when control gets focus
  - do NOT open suggestions when the page gets navigated to or
      light dismiss (aka programmatic focus)
  - DO open suggestions when user tabs to control
