Merged requested to merge halfline/test-case-pipe-confusion into main
pipes need to be written in the write end, not the read end.
This commit makes that change in a recent test added.
Might help with this error message I'm seeing in CI:
/tmp/bin-path-H1UQT1/gnome-terminal: cannot create /proc/38961/fd/6: No such file or directory
Helps: #2781 (closed)
