One of our users found a bug that I honestly cannot believe works

Should be an artifact of using the cached username to show the user card @venarius

Does the username actually change, or just the presentation of the cached username to the user?

Test: @orangeANDblack5

Ok, so the report in the other topic is incorrect. It only affects the presentation of the user card on-click, other occurences of the username within the topic don’t change.

Definitely an unusual case, perhaps @venarius can have a look when he has a few minutes free.
