Fix issue space key preview remains on screen and would not dismiss

The space key preview should be displayed one of the following case.
- Popup preview is enabled
- Language switcher is in action, whether popup preview is enabled or
  not.

For phone number keyboard, popup preview is never displayed even if
popup preview is enabled.
