No window menu on maximized windows, and double-click on titlebar with buttons 3, 6 or 7 restores

Binary package hint: indicator-appmenu

Double-clicking with buttons 3, 6 and 7 on the unity panel (which serves as titlebar+menubar) restores a maximized window. I doubt this is intended. And a single right-click on the panel does not show the window menu.

The behaviour of single clicks is:
- Button 1: focus (correct)
- Button 2: unfocus (correct)
- Button 3: nothing (wrong - should pop up window menu)
- Buttons 4-5: nothing (correct)
- Buttons 6-7: nothing (correct)
- (likely that others correctly do nothing too)

The behaviour of double clicks is:
- Button 1: restore (correct)
- Button 2: nothing (correct) - possibly because it catches single-click first?
- Button 3: restore (wrong - should do nothing)
- Buttons 4-5: nothing (correct) [I was hoping for shading, but this would get very messy]
- Buttons 6-7: restore (wrong - should do nothing)
- (I don't have more buttons available; probably they also trigger a restore)
