List of steps to reproduce (step by step, including full links if applicable):
- Go to Special:CheckUser and do a check (go to the "get edits" page after getting the IP)
- Look for the user creation part of the log
You will notice the result not displaying the correct username of the user being checked. Example (with name generalized) of what it says:
"User account Unknown user was created"
What should have happened instead?:
It should have the username instead.
Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc:
Considering the problem has happened for usernames from July 13 onward, I assume it is related to https://gerrit.wikimedia.org/r/c/mediawiki/core/+/684142?
