Dev channel update to 76.0.172.0 is live

Hi Mike Dominik, both you and Rahsna Asurac seem to be having an issue with our pinned websites.  Can you please help me understand what you are doing and what you are seeing?  I have tried this feature on the latest Dev channel with several sites and it seems to be working as expected for me.

My Repro:

1) Go to some distinct site, I have tried both Imgur.com and Microsoft.com pages.

2) Go to More Menu (...) -> More Tools -> Pin to Desktop

3) Close Dev channel browser, double click on the new desktop shortcut

4) The specific site opens.

5) Double click on the desktop shortcut again, focus is returned to original (and only page).

6) Click on + (New Tab) and go to some site, different from shortcut.

7) Double click on the desktop shortcut again, focus is returned to original, other page is still open.

8) Navigate away from that specific page, like the root of Microsoft.com.

9) Double click on the desktop shortcut again, a new tab is created and navigates to the correct specific page.

Please let me know if you are seeing something different.  We may have a bug in some conflicting setting.  Thanks for your feedback and your help getting to the bottom of this!
