>+        On iOS the arrow keys are identified by special multi character key strings: UIKeyInput{Up,
>+        Down, Left, Right}Arrow as opposed to special key codes as on Mac. When converting the iOS-
>+        specific WebEvent we need to take care to recognize when the key string for the event is
>+        one of these special key strings when computing key code, character code, and key identifier
>+        properties for the WebCore platform-specific event. These details will be included in
>+        the corresponding DOM keyboard events that are dispatched when the arrow keys are pressed.
>+
>+        Unfortunately I ran into <https://bugs.webkit.org/show_bug.cgi?id=189388> and hence could
>+        not write a test for this change.
