This HoC gives you a way to work with co-located fragments that is similar to Relay's FragmentContainer

It supports both fragment maps extrapolation of prop names from fragment definitions.

export default withFragments({
  price: gql`
 fragment ProductDetails_price on Product {

Subject: [PATCH 1/2] Adjust to tray removal in gnome-shell

GNOME 3.26 will no longer display status icons by default, so there is
no system tray we can take over. Take this case into account to avoid
errors, although this alone doesn't give us back status icons - we will
do that in a second step by starting to manage our own tray.
