I actually had a look.  ICCCM says:
" The (x,y) coordinates will be in the root coordinate system adjusted for the
   border width the client requested, irrespective of any reparenting ... "
and layer
" the coordinates will reflect the actual border width of the window 
  (which the window manager might have changed)"

QXEmbed does not adjust for the border width.
Therefore it does it right when the border width is zero.
Lubos says that QXEmbed is allowed to enforce a zero border width policy.
But QXEmbed does not en does not do this.  It solely calls XResizeWindow.

The simplest fix would be to replace all the two XResizeWindow by 
XConfigureWindow to enforce the position, the size, and a zero border width.
For additional safety, another call to XConfigureWindow should probably 
be made when we receive a ConfigureRequest message, before sending 
the synthetic notification.

Lubos, does this seem correct to you?
