[CentOS] Google chrome vs network settings proxy?

I started using chrome on the RHEL7 beta after some firefox hangs -
but maybe this behavior is generic.     I have the system 'network
settings/network proxy' set to use squid on another host for
connections out of the private range we use.   This proxy requires
authentication so I can always tell the first time a browser uses it.
 However, I can start a chrome connection to gmail and it just goes
direct (which happens to work, I just prefer the proxy which will use
a different outbound route).   If I go to any non-google site, it uses
the proxy and will pop up the expected authentication dialog on the
first connection.   Does anyone know (a) why it bypasses the proxy
when going to a google site, (b) why it doesn't have its own internal
proxy settings, or (c) how to fix it?
