is_admin_bar_showing can return true when it isn't

[westi]

is_admin_bar_showing returns true on wp-login.php if you are logged in but it will never be shown.

It shouldn't

That you can go to wp-login.php when logged in, seems to be the real bug here: #14949.

Replying to nacin:

Not 100% sure on that but I can see the argument.

Even if we don't allow access to the page when logged in this bug still exists if the admin bar is shown to logged out users.

[nacin]

Agreed. Patch attached makes sure that wp-login.php avoids the is_admin() check.

If on the other hand you did want the admin bar on the login page, you could still use the show_admin_bar filter. You'd need to attach the admin bar to the specific hooks yourself anyway.
