New Python REPL double-prints completion suggestions

Bug report

Bug description:

If a keyboard interrupt is given while TAB autocomplete suggestions are being displayed, they are re-printed also below the last line, and continue to be re-printed as long as new keyboard interrupts are given.

after the keystrokes int.<TAB><TAB>

<ENTER> makes the last set of printed suggestions disappear, as does typing any printing characters.

Reproduisez le problème dans le REPL Python 3.14 avec int.<TAB><TAB> suivi de pressions répétées sur Ctrl-C, puis examinez les PRs liés gh-128442 et gh-128467 pour comprendre le contexte d’implémentation actif. C’est terminé lorsque les suggestions de complétion interrompues ne sont plus affichées et que la saisie normale ou Enter les efface toujours comme décrit.
