Because of EZP-26238 when you point your browser to:
http://example.com/ezdemo_site_admin/Tests/Article-1
you will get to that page after login. It doesn't work when you type the link to Content Item Tab, for example:
http://example.com/admin/content/location/61#ez-tab-location-view-translations#tab
after logging in, it will redirect to the content view instead of translation.
