fix(wm): ignore polling updates from com hwnds

This commit ensures that what monitor reconciliation is triggered from a
MonitorPoll event, the focused monitor is only updated when the HWND
associated with the event is known not to be tied to a specific (in this
case, the primary) monitor.

This ensures that silent state updates do not occur and avoids
unexpected behaviour when performing operations relative to the
currently focused window on a non-primary display (focus, move etc.)
