When the Edge insider browser hangs, we can't use the feedback feature to record the problem and recreate it in order to send diagnostic data to the Edge team, why? because both of the Edge's and feedback's process hang at the same time.
i'm talking exactly about this:

the Edge process should be separated from the feedback and diagnostic process so when Edge hangs, the feedback process will still be responsive and record what's wrong with the browser and what element or website exactly caused the hang.
