The same problem happens with Debian Buster (currently "testing".) I was
unable to reproduce the problem when running

 (cd subdirectory && tmux split-window)

from a shell prompt.

However, I managed to fix it with the following patch. I'm not sure whether
this means there's a bug in tmux though. Since I can't reproduce the
problem outside OE, it's rather difficult to report it.
