[vive] Video only plays when WIC is pointing at the Web Browser Widget


When I load URL of a youtube video using web browser widget, and points the widget interaction component then it plays fine as soon as I stops pointing the WIC to the web browser widget, the video freezes but the audio keeps playing.
I am working with Unreal 4.22 and HTC Vive Pro. Is this some bug or am I doing something wrong?

I would really appreciate any help.
