Drag/Dropping Window to Maximized Cuts Taskbar (BorderOnly Deco)

[ArchLeaders]

I'm setting up a custom window chrome for my application, but I'm getting some weird behavior with the drag/drop to fullscreen action in Windows 10.

Setting WindowState to WindowState.Maximized works just fine, but when I drag the window to the top of the screen and drop it cuts out the task bar and about 7 pixels off the side of the window.

Is there a way to intercept this behavior and call whatever Avalonia does to fullscreen to the correct bounds instead? Or just another way to fix this?
