What did you do?
I started a video using a HLS stream as its source, waited for the preroll to reach its end, and couldn't proceed to the content. The ad is stalled and doesn't trigger an "ended" event.

What did you expect to happen?
I expected the ad to end, fire IMA's "AD_COMPLETED" event, and resume to the content.

What actually happened?
I can't proceed to the content when the ad ends. The ad is stalled and doesn't trigger an "ended" event. I'm stuck in the preroll ad.
On the webOS Simulator, this doesn't happen with a common mp4 video. I've only been able to reproduce the issue with HLS or DASH streams. Setting the ad's "currentTime" to its duration actually ends it and fires the event, but I can't proceed to the content.

WebOS only supports one video instance at a time, we need implement: #2792
