I used the option showPassthroughVideo = true in my FullscreenView in order to allow video display below my widget content. But there is a problem. At first, when I come to FullscreenView through SidebarView, I can see the video below my widget content. But when I come back to SidebarView, and then go to FullscreenView again, I can't see the video anymore. Can't anybody tell me how to fix it.
