Muxing several subtitles streams in .m2ts with mpegts muxer not working

[Starbuck]

FFmpeg can't mux several subtitles streams in M2TS while it could do (BDMV files are M2TS).
How to reproduce:

% ffmpeg.exe -canvas_size 720x480 -i C:/Users/Me/Temp/title04.mkv -strict -2 -f mpegts -map 0:0 -filter:v:0 yadif,scale=940:400 -c:v:0 libx264 -crf:v:0 19 -map 0:1 -c:a:0 libfdk_aac -b:a:0 330k -metadata:s:a:0 language=eng -map 0:2 -c:s:0 copy -metadata:s:s:0 language=fra -map 0:3 -c:s:1 copy -metadata:s:s:1 language=ita -y D:/Users/Me/Videos/Video 360/DH_title_4.m2ts

The trancoding goes to 100% witout error:

But there is no subtitles in output file.

Same command with -f matroska and .mkv output file works.
