Some comment buttons not being filtered through advanced_forum_links_alter

Issue Summary

I've got an issue whereby moderators who are assigned permissions to edit and delete some forum boards have the 'Edit' and 'Delete' buttons on comments missing the 'af-button-small' class assigned through the advanced_forum_links_alter() function.

The node always has the buttons correctly styled, along with the very first comment displayed (even if on page x). Every 'Edit' and 'Delete' button below this though doesn't seem to get passed into advanced_forum_links_alter() - almost like this is done after this function has been processed (the 'Reply' button always is though).

I'm not sure if this is a problem with the way Forum Access adds these buttons to the comment or a problem with AF itself.
