New windows should only be focused if they are in the current workspace.
Not performing this check can lead to WM switching workspaces if a
window is opened which:
(a) is configured to appear in a particular workspace
and
(b) sends a _NET_ACTIVE_WINDOW message to give focus to
something, e.g. a sub window.
This behaviour was observed with firefox if a session with more
than one tab open was restored at startup because:
"If a Client wants to activate another window, it MUST send a
_NET_ACTIVE_WINDOW client message to the root window:"
