Thread:Extension talk:Password Reset/Broken by trunk version of mediawiki 1.19?

Version tested is: 1.19alpha (Version 93922), here the link during login "Forgotten your login details?" points to a form Reset password: Complete this form to receive an e-mail reminder of your account details. Username: [    ] [e-mail new password].

which is the page: Special:PasswordReset. This page exists WITHOUT Extension:Password Reset being installed. It seems a (different) core functionality uses the same special page name now? Any insights?
