Focus stealing prevention works with applications that implements the
standard _NET_WM_USER_TIME.

It prevents newly mapped windows to steal focus based on the different
time stamps.

It won't prevent an application calling XSetInputFocus() by itself or
using  NET_ACTIVE_WINDOW with a timestamp of 0 (means current time) [2]
as the application is explicitly asking for focus and might base its
behavior on that...
