   exists regardless of which VDO_* adapter is active, so the overlay keeps
   16:9 and correct stacking no matter the underlying player.

   #custom_html_player_div itself has no position set in live2.css (only the

   sizing) once the async videojs() constructor finishes. On the very first
   video panel of a session this gap is wide enough to be visible as a bare
   black box, which reads like a page reload. Opacity (not display:none, to
