Yes, this drop-down panel is outside of my IDE window and is attached to the upper edge of my screen because I have a desktop toolbar attached to the upper edge of my screen.
It should be inside the IDE window and attached to the main toolbar or to the IDE title bar.
Obviously this dropdown toolbar thinks: "The IDE window is maximized, so I will attach myself to the upper edge of the screen, so it looks as I am attached to the IDE title bar".
But the dropdown toolbar does not realize that even when the IDE window is maximized, this does not necessarily mean that the IDE window title bar is attached at the upper edge of the screen. Which on my desktop is not the case because the desktop toolbar is between ths upper edge of the screen and the IDE window title bar!
