add label alignment in nodes in Sankey plot

Dear devs,

Recently, I have been playing around with Sankey plots in plotly. This tool is really great. I have been looking for a specific feature that I couldn't find in the API and in fact I believe it does not exist, yet.
Would it be possible to specifiy the alignment of the labels in the nodes of a sankey plot?
Specifically in vertical orientation, I believe the nodes would look much prettier, if the label may be horizontally aligned with the box.

I would imagine additional keywords for the node-dictionary like "horizontalalignment" and "verticalalignment".
(As it is the case for matplotlib textboxes :
https://matplotlib.org/3.1.1/tutorials/text/text_props.html)

Possibly, this is actually easily implemented, but I could not really figure out, how to do that myself.

Is it possible to add this feature?

L’issue concerne l’ajout de l’alignement horizontal et vertical des étiquettes des nœuds Sankey, mais elle ne nomme aucun fichier source, test ou point d’entrée. Commencez par localiser l’API des nœuds Sankey et examiner la référence liée de Matplotlib sur les propriétés du texte ; cela signifie que les options d’alignement sont prises en charge et documentées pour les graphiques Sankey orientés verticalement.
