Performance optimization for webinar pages

Live chat and audience reporting don't work while the stream is offline

Problems with WYWN plugin events

On a dedicated replay split webinar users are not locked to one webinar once they register

On a split webinar the "Attendees Online" section displays the names from the names list instead of "Guest-#" names

Dedicated Replays: If the registration page is enabled, and the webinar end date has passed, the registration page says that the webinar is still available when it is not. Attempting to register does not display an error message

Switching to landscape/portrait mode (mobile), refreshing the page, or going full screen after answering a poll shows poll question again
