A DESCRIPTION OF THE PROBLEM :
Clicking on a focused item in menu bar should toggle focus. This fails if menu contains no sub-elements. The first click grants focus but subsequent clicks have no effect.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Launch test app and click 'A' repeatedly. Note that focus never departs. Click 'B' to demonstrate proper behavior.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect focus to be revoked on second click of 'A' menu.
ACTUAL -
Focus remains.

REPRODUCIBILITY :
This bug can be reproduced always.
