Compare mode: markers are only generated in one language

60 r26928

I have imported packaged demo (en + fr)
When I access the compare mode, everything seems fine, but if I switch my language, I have nothing highlighted, whereas I hadn't published my page in any language.
I have renamed a page in my top menu. Now, the whole navigation container list is highlighted (but only this part of my page)
When I go back to my first language, my whole page is still highlighted, excepted tha navigation container list
