If you have your own custom implementation of the XEMBED spec, yes
it is. There is no way for an XEMBED client to say "I never take
the focus" - the way an XEMBED client indicates that it never
takes the focus is that when it gets a XEMBED_FOCUS_IN message
with FOCUS_FIRST/FOCUS_LAST, it immediately sends a
XEMBED_FOCUS_NEXT/PREV message as appropriate.

With this addition, if you find the XEMBED_FOCUS_WRAPAROUND flag
in the FOCUS_IN message, you should propagate it to the 
FOCUS_NEXT/FOCUS_PREV message.

This could be important if the tray was the only thing in a separate
toplevel window.
