Powerline: Les segments de coque "Au-dessus à droite" sont alignés à gauche sur la configuration multiligne

J'utilise Powerline avec des poissons de tmux. J'ai essayé de configurer une invite de shell multiligne et j'ai reçu le comportement suivant sur fish et zsh:

Je n'ai pas encore essayé de reproduire dans une VM, donc s'il y a une chose évidente que je fais mal, veuillez le signaler.

Si cela aide, voici la sortie de env $POWERLINE_COMMAND shell right | xxd :

00000000: 1b5b 306d                                .[0m

Et voici les invites de poisson:
