It's not a bug, that's working as expected. We have it setup so that if the window is not maximized when you start dragging it, it doesn't show the selector overlay. If it is maximized to a split already and you drag it to another one, it should be showing the overlay.
Another function that might help you out is the "Move Window to Different Monitor (show monitor selector)" function on the Settings > Functions tab. You can set that as a TitleBar Button, or assign a key combination to it, and then you can use that to send a window maximized to a different split without having to drag it.
Hope that helps!
