Interesting! I've confirmed the issue but it actually seems like it's an iTunes bug. I tested the same scenario without DisplayFusion running and just using the Windows taskbar, and iTunes behaved the same when maximized.
Could you try it out on the screen with the Windows taskbar without DisplayFusion running to confirm?
Thanks!

Nice find! I'm ashamed to have assumed it was DisplayFusion right away- what a careless job by the Apple testers!
