I don't see how this is
Because your last pipe will pipe BOTH output of `echo` AND `head` with
delay due to fork, head output will comme after. try this:
echo -e '9\n4\n3\n2\n8\n7\n3\n1' |tee >(head -1 >&2) |tail -1
or
echo -e '9\n4\n3\n2\n8\n7\n3\n1' |tee >(head -1 >&2) >(tail -1 >&2) >/dev/null
...

Not a bug.
If you leave
if u d try echo .. | tee >( >/dev/null ) | tail -1
i havent tested, but im trying to say, the stdout by head seems to be taken
i mean heads stdout prioritizes
im not sure.. ppl ( that know .. ) .. write about it :)
