ContextMenu parent menu closes when submenu opens

Test link

On desktop, sub-menus can be opened by hovering on the parent menu, but on mobile, hovering is not possible, users are required to click on the parent menu to access the submenu, but currently whenever I click on a parent menu item, the whole menu closes (and the submenu opens at some weird location, described in #1847).

I expect the menu to persist until I click outside or click on an option that doesn't have a submenu.
