User's account is still disabled after being enabled by Admin and no successfully login is performed

1. Login as Admin
2. Create an user (e.g. U1)
3. Go to Administer Wiki > Users & Rights > Authentication
4. On 'Failure Strategies' select 'Disable account' and Save
5. Logout
6. Try to login with user's name (U1) and a wrong password 3 times (default setting) in order to get the message that the user's account is disabled
7. Login as Admin
8. Go to user's (U1) profile page and enable its profile
9. Logout
10. Try to login again with user's name (U1) and a wrong password

EXPECTED RESULTS

The message 'Error: Invalid credentials' is displayed. The user has 2 remaining tries until its account is disabled again.

ACTUAL RESULTS

The message that the user's account is disabled is still displayed. If logging in with Admin and go to the user's profile page, the account is disabled indeed.

However, this happens if the user does not first login successfully after its account was enabled by Admin.
