/* AVBK_Frontend_Admin_Menu injects "Administratie" as a top-level item,
   usually the rightmost in the header nav. The core Navigation block
   opens a nested submenu (a submenu's own submenu, e.g. "Leden"'s
   subitems) further to the right of its already right-positioned
   parent, which pushes it off-screen here. Flip nested submenus to
   open leftward instead — !important because the core block-library
   styles it overrides load with matching specificity. */
