I open the Gallery item, video is there, it plays… all good.
Than I close the Item http://prntscr.com/lcv4dg using X up-righ corner. The Gallery item closes, but video still plays (i can hear it)
It’s not a bug. Because there is no relation to the modal close button with YouTube video stops playing. In this issue, you need to pause the video before close the modal.
We are really sorry to say that there is no code available and you could try JAVA to implement that function. However, we are not sure that will work or not.
