Clicks pass through to widgets behind context menu

[lightningorb]

Describe the bug
When clicking on the context menu items, the items behind it get clicked too

Expected behavior
Press events should not affect widgets behind, e.g if the context menu is over a text input, then the text input should not get the focus

I add below method to my major application menu - class inherited from AppMenu.

    def collide_point(self, x, y):
        for item in self.walk():
            try:
                submenu = item.get_submenu()
                if submenu.visible and submenu.self_or_submenu_collide_with_point(x, y):
                    return True
            except:
                pass
        return super().collide_point(x, y)

This helps me, when context menu is rolled up from AppMenu. Then clicks don't pass through.
