/* Fullscreen mode — v2.1.1
   The black-screen-after-N-cycles bug: fullscreen enters correctly but the
   content becomes invisible after several enter/exit cycles when logged in.

   Root cause: Chrome's compositor can drop the content layer of a position:fixed
   element that is also the :fullscreen element, after enough layout thrash from
   entering/exiting. The fix is to pin all child layers with will-change:transform
   so the compositor KEEPS them alive across transitions, and to use
   contain:layout to isolate the fullscreen element's layout from the rest of
   the page (preventing the WP admin bar and Divi's layout from interfering).

   We keep position:fixed because removing it causes Chrome to auto-exit
   fullscreen (the element collapses out of viewport coverage). */
