Description gatan61703 2025-11-16 16:07:41 UTC 
1. Create an identity with a punycode domain, for example, 點看.com. Put info@點看.com into Identity's "Email address" field and save.
2. Observe that new messages under this identity get created normally and "From:" field is correctly filled with "info@點看.com".
3. Try replying to an existing message in the mailbox using this default identity. Observe that "From:" field is empty now.
4. Pick the same identity again from the picker and watch the "From:" field getting the specified value.
5. Change "Email address" field in the Identity editor to info@xn--c1yn36f.com. Observe that the problem is gone now - both replying and new messages now display the pre-filled "From:" field every time.
