BUG ID: Bugzilla bug 6821 Fix for 5983 will not always update hover correctly.
STEPS TO TEST: Move the mouse over the text “Hover here” until it disappears and “Wait” appears, then DO NOT MOVE the mouse until the end of the test.
TEST PASS: After a second, you should see “Only green now” over a green background. No other colors should be visible.
