 Summary of the bug:

 When overlaying subtitles (idx/sub), the very last subtitle is displayed
 only very briefly and the duration of it appears to be ignored by ffmpeg.

 All files attached.
 The idx/sub has 3 subtitles at 2 seconds, 4 seconds and 6 seconds.

 testhardcode.mkv shows the first and second subtitles with a normal
 duration, and the last subtitle is very briefly flashed.


 How to reproduce:

 ffmpeg -report -v 9 -loglevel 99 -i blankvideo.mp4 -i test.idx
 -filter_complex "[0:v][1:s]overlay=eof_action=pass[vout]" -y -map "[vout]"
 testhardcode.mkv
