What actually happened?

Shaka throws 3015/3016 errors when encrypted content is added to the buffer.
There are content workarounds which alter init segments, but they're not enabled for webOS now. However, enabling them seems to be not enough to prevent this issue from happening.

Are you planning to send a PR to fix it?
