Main window is not closed automatically after clicking on desktop

I set the [close when not focused], but I do not work when I am on the desktop, will only be closed when I click on other programs, because I clicked on the desktop and CopyQ is not focused, at this time I can not use the shortcut keys to close, and I can only click on the CopyQ window, and then press the shortcut keys to close, I think this is not a good idea
