Given that you've removed the reset-on-process-relaunch behavior, make sure you
test that bluetooth works properly after a crash.

The following repro steps could help (and would make a fine browsertest):
 1. Load a test page and interact with bluetooth.
 2. Using the task manager, kill the process, producing a sad tab.
 3. Hit F5 to reload the page.

Done.
