Background
mailman3 allows to associate multiple email addresses to your mailman3 account so you can decide to receive emails sent to lists on different email addresses as you wish.
Steps to reproduce
- Have a Wikimedia mailman3 account.
- Subscribe to a mailing list, e.g., https://lists.wikimedia.org/postorius/lists/pywikibot.lists.wikimedia.org/.
- Access subscription management: https://lists.wikimedia.org/postorius/accounts/list-options/pywikibot.lists.wikimedia.org/.
- Change your subscription email address selecting a different one from the dropdown (even if you don't have multiple addresses registered the dropdown will show the address you use, one tagged with being the main one, and the other one the non-main one; choose the main/non-main as appropriate for this).
- Confirm changes
- Receive confirmation message on top.
Actual results
Confirmation message is broken and reads (translation): Your subscription was changed to %s.
Expected results
%s should, I guess, a properly-formatted email address e.g. you@domain.com.

Note
mailman3 interface from me is in Spanish as that is my browser language; I don't know if this is happening on other languages (see T281747). This might be an issue with the Spanish translations or be a general software bug.
