This problem arose from some memory leak fixes when making such calls, it's in a different pull request already take a look at the danielr-197 branch.

Yep, danielr-197's variant looks better. Could you also comment the second commit?

Right. I had gone through all events in an attempt to cleanup any memory issues, I did notice making some of them weak would get garbage collected too early. With that one there was noway to stop the event listener so made it weak. Is it being cleaned up too early and affecting animations ?

Let me know how it's being affected and I'll what I can do. It looks like complete callback and update events.

Yes, update callback cleaned to early. The progress bar in scrubber stops when the scrubber stays displayed for some time. It looks like the problem is that the progress bar update callback is an anonymous function, so, it gets cleaned too early.

OK taking this back and let the GC deal with it.

#216 it's within this branch for now.

They both should be merged soon thanks it is an issue people are picking up ;(
