A store will not load its own records into its data member if
events are suppressed.  The store uses the onDataRefresh event
to trigger loading the records into data. It will properly
return the records to the callback registered during the .load()
call, but will not load them internally.  SDK Version  It
happens in data/Store.js, on line 1901 in the onProxyLoad
method. If the proxy was successful, it attempts to fire the
'datarefresh' event. It also sends a callback with that firing
that should have been called after all the event handlers
(Store.doDataRefresh). However, if you trace into the
mixin/Observable class fireAction and then doFireEvent, we find
that the method returns immediately if events are suppressed,
not bothering to call the registered callback.
