  • Displays element fullscreen and resolves promise when done.

    When supplied, options's navigationUI member indicates whether showing navigation UI while in fullscreen is preferred or not. If set to "show", navigation simplicity is preferred over screen space, and if set to "hide", more screen space is preferred. User agents are always free to honor user preference over the application's. The default value "auto" indicates no application preference.
