When I switch to one of my workspaces with Chrome, it jumps to the other Chrome workspace
The only work-around I've found for this is to move the window that keeps stealing focus to another workspace. If I move it back to the previous workspace it will exhibit the same behaviour, so I need to delete that workspace and create it again, and then move the window back to it.

Upgrading to 10.13.2 didn't fix it for me.

Update: Upgraded to 10.13.3 and the issue is still there.
