 Summary of the bug: When I'm reencoding softsubbed mkv files, with .ass
 subtitles, in some cases some formatted subtitles are disappearing, I've
 cut out a sample from a file, so it should be simple to reproduce the
 error.
 I'll include the original file, and the reencoded file, so you can see the
 difference, the problem occurs at 0:02.

 How to reproduce:
 {{{
 % ffmpeg -i "(Hi10)_Kokoro_Connect_-_03_(720p)_(rori).SP-002.mkv" -acodec
 copy -vcodec libx264 -scodec copy -profile:v high10 -preset veryslow -tune
 animation -refs 16 -bf 8 -me_range 24 -aq-mode 1 -crf 22 -psy-rd 0.4:0.0
 -subq 10 -trellis 2 -rc-lookahead 40 -qcomp 0.6 -aq-strength 0.6 -map 0
 "(Hi10)_Kokoro_Connect_-_03_(720p)_(rori).SP-002.enc.mkv"
