Video keep playing in the background even though its marker is not scanned

[BhaktiugpMrAR]

Hi, it is my first time developing a web AR app using 8thWall and A-Frame. I start using Flyer example and edit its model, video target, and content. Then I found two issues, that is:

• Video keep playing in the background even though its marker is not scanned
• Video still can be played (by tap) on its last scanned marker location (without a scanned marker in camera)

I wonder how to fix those, thank you very much and have a nice day!
