Steps to reproduce the problem:
1. Create a chrome extension that makes calls to gapi in a background script, ex: 

    var request = gapi.client['yourapi']['yourmethod'].search(resource);
request.execute(function(resp) {
  if (!resp || resp['error']) {
     callback(null);
  } else {
     callback(resp);
  }
});

2. open the devtools for for the background page of the extension
3. cause the extension to make the call.
3. look at the network tab.  

What is the expected behavior?
The network tab should show the call to the API

What went wrong?
Call is not shown in the list of network requests (but request does execute and results are returned)

Did this work before? Yes Not sure.  Definitely within lat 6mo
