 Summary of the bug:
 Attempting to mux a h265 mkv(Video.mkv) that contains hdmv_pgs_subtitles
 with an mkv(TrueHD.mkv) containing only TrueHD 7.1 audio results in this
 error.

 [matroska @ 0000024dcd75c1a0] Application provided invalid, non
 monotonically increasing dts to muxer in stream 5: 12554 >= 12552
 av_interleaved_write_frame(): Invalid argument
 size=       2kB time=00:00:12.55 bitrate=   1.2kbits/s speed=N/A
 video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB
 muxing overhead: 5425.714355%
 Conversion failed!

 If I don't map the subtitles no errors occur and the files mux normally.

 Extra Details
 {{{
 The video file was originally AVC from a blu-ray converted to h265
 ffmpeg -i file.m2ts -map 0:0 -c:v hevc_nvenc -b:v 6M Video.mkv

 The audio was copied from the blu-ray
 ffmpeg -i file.m2ts -map 0:2 -c:a copy TrueHD.mkv
