No it's not the cause. I still see them on b2g-inbound + gaia master,
and they were here before I landed 924032 :

In general, using mismatched combinations of gecko and gaia is not

other issues and end up in an endless cherry-picking game (look at the
changes happening lately because of the webidl-ification of contacts).
