Opening a new window should not have pinned tabs

[inian]

Description

Whenever I open a new window, I see the pinned tabs in the newly opened window as well. In Chrome, pinned tabs are not opened when opening a new browser window. I think this makes more sense since I don't want the same tabs to be opened again and again for each browser window I open.

Steps to Reproduce

1. Pin sites in a browser window
2. Open a new browser window

Actual result:
Pinned sites open automatically on new browser window launch

Expected result:
Pinned sites do not open in the newly launched browser window

Reproduces how often:
100%
