On iOS 13 vmap using .m3u8 stream continues at wrong time after mid roll

[Yozine]

When I play the http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 in combination with the kVMAPPodsTag, the AdvancedExample project crashes in VideoViewController at line 204 (on contentPlayer!.currentItem, force unwrapped nil value).

When I guard against the crash, the content does play, but after the mid roll, the stream continues at 0.0, rather than at the 15 seconds marker the mid roll started at. I can reproduce this issue (currentItem unavailable) in my own application with a FairPlay stream. Then, the SDK tries to seek to the closest point in time (which regresses the user several seconds up to a minute in the stream, somewhere before the mid roll.

Could you help me figure out why this happens on iOS 13? On iOS 12 and previous, this issue does not occur.
