I have similar output in session buffer too. Here is the output in my session buffer.

When I press Tab key to expand upper headline. I check the inline src block session buffer, here is the output:

I also try to add "sleep 1;" command before "mpv ..." command to delay
mpv executing. Still not success.

Don't know ob-shell which part did your said "echo" commands. I don't
know where to dig this issue. Hope you can help. Thanks for your
reproducing problem and dive in.
