when a comment is being added on a page that is not part of its parent entity there is no function for looking up the og of the parent comment and modules like notifications_team can not retrieve that info.
the menu structure, comment/reply/1/1 requires a contextual hook.
This issue has come up in response to .
I made an extension module http://drupal.org/project/og_context_comment here. In the issue , Amitaibu asked me to patch og_context core and provide it so this is a place holder for my patch.
