 For users extending the back end of wordpress, sometimes custom pages
 added to the main menu will not be flagged as the current page because of
 unexpected aspects such as additional GET data.

 The problem is, setting this directly using a filter like {{{admin_menu}}}
 does not work due to {{{$subpage_file}}} being set later on (needs
 confirming), nor does it make sense due to context.

 At the top of {{{menu-header.php}}}, there is a filter called
 {{{parent_file}}}, used to allow plugins/themes to move the submenu tabs
 around, a suggestion would be to add a {{{subpage_file}}} filter, allowing
 plugins and the theme to modify the compared url to check the current
 page.

 Would add a patch, but away from my development environment.
