I can't seem to reproduce this each and every time with the steps as originally entered. There seems to be something more going on. I am trying to find a way to always reproduce it.

I just able to reproduce it by inserting these steps:

2b. open a few more tabs

3b. Open a few tabs in the 2nd window
3c. Open a 3rd window

5b. Close the 3rd window

No, that doesn't do it reliably, either. I will keep trying...

One thing to note: in step 4, when I close the original window, it tells me how many tabs I have open and asks me if I really want to close the window, as expected, but the tab count INCLUDES the pinned tabs

I was just able to reproduce it three times in a row.

Make sure to close the 3rd window last. There were no open tabs in my 3rd window. Not sure if that matters.

I do have an override for the New Tab Page. I use the extension "New Tab Override" to get a BLANK New Tab Page. Not sure if that matters.

Trying very hard to get you an absolutely reproducible test case.
