In Tweaks I have my focus mode set to "Focus on Hover", which is
described as, "Window is focused when hovered with the pointer.
Windows remain focused when the desktop is hovered." Nevertheless,
when I hover over a window and then move the house so that it is over
the desktop instead of the window, the window loses focus, if I have
the Desktop Icons NG extension installed and enabled. According to my
setting and description of same, the window should keep focus. If I
disable the extension focus behaves as expected and desired.
