iOS: keyboard breaks when sliding on space bar

[codefrau]

Sliding in space bar should move the cursor. Or at least not break input. It only works again after hiding and showing the keyboard.

This would also be useful for Android (at least the Gboard keyboard supports this gesture, too). By the way, tapping on autocorrection in Gboard also does not delete the first word before, this might be related :)

I also made the sliding generate arrow key events. Hacky but works 188ff82
