Bug report

Bug description:

I've been playing a bit with the new REPL, it's so awesome! (thanks to @pablogsal and @ambv for the core.py episode 💌 )

I noticed a strange behaviour of the tab completion, whereas upon pressing the tab twice to show available options, the >>> prompt jumps down and the options are displayed above it. Please tell me this is a bug and not a feature. 😅

After a single TAB

After the second TAB

This is on Fedora 39, built with ./configure --with-readline, in Terminator terminal.
Apologies if I missed something, happy to provide more info.

CPython versions tested on:

3.13

Operating systems tested on:
