[[ Bug 19536 ]] Ensure parent is submenu

montegoulding · montegoulding · commit 39471c24e2d8 · 2018-03-14T10:36:02.000+11:00
This patch checks that the parent of the parent of a menu is a button.
This will be the case if it is a submenu and we should continue iterating
the menu tree to confirm the click was outside a menu.
