With several REPLs bound for a language the pane always asks which, as documented, whether or not a program runs in each

Only REPLs with a program running were counted, so with two bound and
one at its shell prompt the text went to the other without a word,
and which REPL got it depended on what happened to be running. All
bound REPLs are offered now; one chosen with no program running is
sent nothing and says so.
