Fixed issue 35580. Keys will no longer be duplicated if external scanner is not connected
The main problem was that for some reason, in iOS, keypress event always happens, but the keyup event only happens in case there is no external keyboard or scanner connected and the virtual keyboard is used instead, which means that when the virtual keyboard is used, both events are triggered, and the keys appear twice. Therefore, the solution has been to completely disable the use of the keyup event in iOS, and use only the keypress event. No change of behavior is required in other platforms.
