Focus on hover causes problems with software features that open the file explorer

[Thomas Hepworth]

I enabled focus on hover in ubuntu. Whenever I follow a path like file->open in a piece of software (eg, VSCode) there is a very small delay while the "open" button disappears and the file explorer opens. During this delay my cursor is over the main program window, so this gets granted focus and the file explorer window opens behind it, which is very irritating.

Many programs will freeze while you are selecting a file to open, and it can give the impression something has crashed when the file explorer window is hidden behind the main window.

I would propose an optional delay in focus switching if a window has just been opened in order to allow a new sub-window to appear beneath the cursor, before focus switches to the original window again.
