Window on screen 2 jumps to screen 1 on resize. Seems like a bug.

Chrome version 85.0.4183.102 on Windows 10 build 19041.

I'm trying to compare similar content on two screens, both resized to the same resolution, and I have to check about six different, for each. 

Resizing window 1 - no problem. However...when I resize the second window, it jumps over to the main screen to be right on top of the first. I keep having to move it back over. This is annoying.

I'm not seeing anything in settings for the extension that could explain this, but maybe I'm missing something.
