login failed with authentication pop-up still on

[monzug]

tested in Chrome, Alpheios Reading Tools 3.0.4.93
Alpheios Components 1.5.0

the first attempt to login was apparently with a wrong combination of id/psw. the authentication pop-up stays in the front, while you can see the message in the background that I am successfully logged in as user test. when I close the pop-up (it should disappear automatically when the authentication is successful) I got the authentication failed message on the login panel.
weird scenario, indeed
