Reproduction steps

Open the mobile beta
Log into an instance that has usernames set as the login method
Open Dms with anothet account
Click on the Accounts name in the top
Observe that the accounts username is shown with the hidden #0000 tag

Expected behaviour

The #0000 tag stays hidden like everywhere else on an instance where tags are set to none i havent tried this on an email instance with tags disabled but i dont see a reason it should be any different there
