Coming to this a bit late, but:

This seems inconsistent with the effort that we made way back in 2002
(workers/17265 and 17297) to be sure the "jobs" command works in
subshells.  If "jobs" works (which it still does), why shouldn't
$jobstates remain valid?

This is independent of other behavior on the left side of pipes, etc.,
such as the "echo ${a::=2}|cat" example later in the original thread.
