That's not overriding the window manager, it's overriding what the user wants. IIUC, I explicitly told the window manager to ignore what the program tries to do about the placement of the windows it creates, and yet the window manager still allows the program to do (part of) what it wants rather than what I told the window manager to do about the window placement. So either the window manager is ignoring what I'm telling it to do, or the program is able to override the window manager, or both. Either way, what I´m telling the computer to do is being overridden, and that is not acceptable.
