Browse Source 
Makes it consistent with the MRU and improves the behavior:
- considers MRU's debounce
- fixes problematic cases where focus changes to non-Layout and back

// Update the previous focus but only when staying focused on the layout.

// Case 1: opening and closing exclusive-keyboard layer-shell (e.g. app launcher). This
// involves going from Layout to LayerShell, then from LayerShell to Layout. The
// previously focused window should stay unchanged.
//
// Case 1.5: opening layer-shell, in the background switching layout focus, closing
// layer-shell. With the current logic, this won't update the previously focused
// window, which is incorrect. But this case should be rare.
//
// Case 2: switching to an empty workspace, then hitting FocusWindowPrevious. The focus
// should go to the window that was just focused. The keyboard focus goes from Layout
// (with Some surface) to Layout (with None surface), so we update the previously
// focused window.
//
// FIXME: Ideally this should happen inside Layout itself, then there wouldn't be any
// problems with layer-shell, etc. Or a similar problem now with the Overview where we
// don't update the previously focused window because the keyboard focus is on the
// Overview rather than on the Layout.
