Mojang priority can still be changed by some users

When this was fixed the first time, I noticed a bug report WEB-2547 by user Dxlxn Cxoxlx/Fatal Error.

Apparently there is still a way to change the Mojang priority as this user is still doing that on his bug reports. He posted a workaround on his bug report that is probably the way he manages to do this still:

Workaround

1. Click Configure Fields
2. Uncheck Mojang priority
3. Recheck Mojang priority
4. You can now change the Mojang priority
