* SUMMARY
Sending lots of unnecessary CSS.getNamedFlowCollection requests on reload

* STEPS TO REPRODUCE
1. Inspect <http://bogojoker.com>
2. Reload
3. Reload
4. Reload
  => Lots of wasted traffic
  [native code]: CONSOLE LOG request: {"id":303,"method":"CSS.getNamedFlowCollection","params":{"documentNodeId":87}}
  [native code]: CONSOLE LOG response: {"result":{"namedFlows":[]},"id":288}

Apparently FrameTreeElement.onexpand gets called for every resource added, and each time it requests the flows.
