cubicweb #3182874 stuck in the login window [open]

In any application with anonymous access enabled, there's no way to leave the login popup after performing the following actions:
* click on the "login" link,
* a login popup appears,
* leave the identifier/password fields empty and click on the "login" button,
* a new popup appears, with an error message at the bottom,
* clicking on "cancel" or hitting the "Esc" key should bring back to the initial page, but it doesn't. The popup cannot be removed - unless you reload the page of course.
