Steps to reproduce the problem:
As Issue 594950 noted, Chrome hangs completely with devtools open in a tabs with heavy websocket usage.

Our web application downloads several 100s mb of data via websocket in a worker. With devtools closed, the experience is perfect, frame time is 16ms. With devtools open, even while not looking at the network tabs. The browser and all opened tabs/instances hangs completely (no refresh of the UI at all) during the entire transfer which also takes much longer than usual. 

I understand from #594950 that moving the websocket data across process for the purpose of the network inspector is the issue, but I wonder if that could be disable. 

What is the expected behavior?
Being able to use devtools.

What went wrong?
All windows/tabs of Chrome hangs for 30-60s or until the websocket data transfer stops.

Did this work before? N/A
