When the focus is transferred to a JEditorPane+JScrollPane by tabbing to
it, the movement keys do not work correctly inside the JScrollPane.

Hitting a movement key (arrow keys, PgUp/PgDown, etc...) moves the
scroll pane to the proper location, but produces a beep. This makes it
essentially unusable from the keyboard, because it will beep every time
the user inputs a navigation command.

This occurs in every app that I've tried that uses a JEditorPane inside
of a JScrollPane, including SwingSet2's JEditorPane demo.
