Displaying a JToolTip causes text bounding box to disappear in JButton.
Repaint of window (Uncover event) redisplays text bounding box.

To reproduce bug:
Please compile and run the following code:
- Hold the mouse over a JButton for a couple of seconds.
- Note that JToolTip is displayed.
- Move the mouse slowly over other buttons.
- Note that JToolTip is displayed for each JButton
- Note that text bounding box disappears as JToolTip is displayed.
- When text bounding box disappers minimize application window then open it again
- Note that text bounding box is displayed again.
To activate and diactivate JToolTip from keyboard press "Ctrl+F1"
- Select a JButton
- Note that text bounding box is displayed
- Press "Ctrl+F1" to activate JToolTip
- Note that JToolTip is displayed for the selected JButton
- Note that text bounding box disappeard
- Minimize application window then open it again
- Note that text bounding box is displayed again
