Double click on a window's titlebar is transferred to desktop

[Arham Amouei]

Hi. In ubuntu 20.04, whenever I double click on the titlebar of the window of some programs (including: firefox, simplenote, geany, visual studio code, etc.; excluding: gedit, evince, nautilus, etc.), the double click is transferred to the desktop. For example, if behind the titlebar of firefox, at the (X,Y) position of mouse pointer, there is a folder icon on my desktop, that folder gets opened after firefix window is maximized/unmaximized.

However, if right behind the titlebar there is another window (not desktop), the double click is not transferred to that window or to desktop.
