Trim MKV without reencode AND keeping subtitles?

[kingmustard]

I have an MKV video file (AVC H.264 video stream, AAC LC SBR audio stream, SRT text stream).

When I trim it (to the nearest key frame) with MKV Cutter 20170625, I get a video file called "video_withoutSubs", with no text stream.

When I trim it (to the nearest key frame) with avidemux 2.7.6 (Copy / Mkv Muxer), I get a video file with no a text stream.

Anyone have any ideas?

Was the SRT file part of the original MKV, or what I call a "side load" file that players will grab for subtitles if found in the same directory?

It's part of the file/container.

Depending on where you trim the video, the timing in the SRT file could be slightly (or wildly) off.

It's possible to use mkvmerge to copy out the parts you want, but I'm not sure it would be as "clean" as doing it with an editor, where you can make sure there is a key frame at the start. I've tried this before with "all in one" files, and the key frames are as much as two seconds off from where the actual video split should be.
