I am running macOS Mojave
10.14.4 with Books.app version
I use multiple desktops. When I open the Books app on one desktop, and then switch to another desktop, the Books app window shows on that desktop as well.
Even worse, any open Books app window pop in front of all other windows on that desktop.
I've tried assigning the Books application to a specific desktop, to all desktops and to None, and did not see any change in behavior.
This only happens with the Books app on my system.
What may be potentially causing this? How can I keep Books app window restricted to a single desktop?
