Short description of error
Submenus sometimes don't show.
Exact steps for others to reproduce the error
- Pick a submenu just above or below a divider.
- Quickly move the mouse to the divider, passing through the submenu on the way, and then stop moving the mouse. If the menu opens, try again.
- Wait for a tooltip about the passed-over submenu to appear.
- Now actually move the mouse to the submenu, and note that the submenu doesn't open (unless clicking, which isn't usually needed for opening submenus).
Steps 1-4 can occasionally happen by accident, which can then result in confusion since the menu seems to be missing.
