appears to be 0.16.0 specific; unable to repro on 0.15.310. Moving back to 0.16.0

Step 3 seems very odd to me. Absolutely nothing happens between the time that the browser shuts down and the time that it starts back up again. If there is a timing issue after shutdown the problem may be related to shutdown not completing in a normal time

I see a completely different issue in master which is that it reopens with the first normal tab active instead of the pinned tab

[bridiver]

didn't notice it was windows only, but mac also has the wrong behavior. Not sure why they would be different

Will be ready to retest with the next build. Stay tuned...

I think this is fixed, please re-open if it doesn't pass.

Confirmed fixed on Windows 10 x64 😄
