So that I can consolidate likes, shares and comments across canonical and non-canonical presentations of my content I set And use the canonical url of og:url on my non canonical pages.

Thanks to help on an earlier question this now all works in terms of aggregating comments and likes.
But, on my non-canonical pages I extend the title.
Canonical title is of the form [section][item] Non-canonical title is [section][item][context]
Now when adding a comment to the non-canonical page and 'also posting on facebook' the created post has the canonical title (and in fact the canonical url)
Even if I accept the argument that I shouldn't extend the title on the non-canonical pages, I can't accept that posts created by adding a comment to a non-canonical page must have the canonical url...
So is there anything that can be done about this? How do others manage to share the non-canonical context whilst maintaining the aggregation of comments across canonical/non-canonical pages?
