Hi Team,
If we try to notify or tag a user by typing @user-name and there is another user with the name @user then the second user will get the alert instead of the first one, even if in the editor we explicitly selected the right user
This happened to me when I tried to alert @aman-singh
Note: I think that this is the same bug not only if the user name include "-" but any user who which another one use the first part of his name, but I did not examine this deep since we do not have sandbox for testing
