ArrowKey Handler in LiveCode 8?

If there isn't a focused object, arrowkey is supposed to be sent to the
card. This isn't happening in 8.

If you place an additional object (like a scrolling list field) onto the
card and click it so that it has focus, and then hit the arrow keys, your
object to move will behave as you expect.  arrowkey is sent to the focused
object, then passed up to the card. Its this bug.
