Links to anchors work if the user is logged in when she clicks them but if she is not logged in she will get the login page and then be directed only to the page from the link, not to the anchor in the page.

For example:
clicking this link while not logged in should go straight to the anchor:
http://servername:8090/display/test/Anchor#Anchor-test
instead, after logging in the browser is redirected to:
http://servername:8090/pages/viewpage.action?spaceKey=test&title=Anchor
when it should redirect to:
http://servername:8090/pages/viewpage.action?spaceKey=test&title=Anchor#Anchor-test

To reproduce, create an anchor, then a link the anchor. Log out of Confluence and click the link to the anchor.
Result:
After you log in you are directed to the top of the page on the link.
Expected result:
After you log in you should be directed to the anchor on the page not the top of the page.
