Segments are skipped in HLS video with discontinuity tags

### [REQUIRED] Content description
When playing an HLS video with Discontinuity tags, some of its segments are skipped.
It does not happen with all HLS videos with Discontinuity tags, but on the same time, the streams with such problems are able play successfully in both Safari and QuickTime.
The problem happens approximately at playhead position 1m 07s
I played the video using ExoPlayer Demo.

### [REQUIRED] Link to test content
I'm emailing a couple of tests streams. Both share a similar m3u8 segment file, but one of them has the problem while the other does not.

### [REQUIRED] Version of ExoPlayer being used
ExoPlayer version: 2.10.2

### [REQUIRED] Device(s) and version(s) of Android being used
LG G7 ThinQ Android 8.0.0
Nexus 6P Android 9.0

### [REQUIRED] A full bug report captured from the device
I'm also emailing the bug report.

Thanks
