After writing the comments, did some more experiments with the REPL that suggest the need for different or maybe just additional changes somewhere (here? code.II?, IDLE?). I will report on the issue tomorrow. Consider these for now.

@Mariatta Backport are mostly not working for the last hour.
And when it did once, the PR number and link did not appear. I found the backport of #20646 by trying #20647.
