Windows that set empty input shapes get n_rects of 0 when querying them later, which makes sense, but the code that interpreted the result translated it into a NULL input shape, which meant it was the same as the bounding region. As such, an empty input shape would actually get interpreted as a full input shape! We, ourselves, set an empty input shape on tray icon windows in gnome-shell since we would handle the picking ourselves. This meant that we'd actually get the MetaSurfaceActorX11 when hovering over the tray icon, instead of the ShellGTKEmbed that we capture events on and react to. This fixes weird tray icon behavior in gnome-shell.
