There seems like a redirect happening after the anchor is called. The page seems to go toward and anchor and flicks back to the top of page. I do see an anchor called in the url then I see the url change to #content=wiki&action=openDocument&documentId=3A6837DCD3DDC54CCA257ACE004B4D0C
I have been busy with other things, but I will have a look when I get a chance to see if there is a redirect of some sort after page load.
