I'll have a look.

I had seen those modifications on repository, and I copied the code from
repository to try the new sync feature and it worked nicely, but I had
to update manually the code installed via packages.
what bothers me is no error is raised on current behaviour. I'll keep
this problem aside for the moment as 4.4 workaround worked.
