I'd call it a bug in the rendering engine.  There is certainly 
nothing I know of in the specification that would allow the overwrite.

Have you tried just a simple XSL-FO instance that illustrates the 
problem?  If you post it to the list, then I and other can try out 
the fragment in other rendering engines.

A starting fragment is below ... simply replace the text and add the 
properties as needed, then run it in FOP to prove to yourself there 
is a problem, then post it to the list for others to try.

I hope this helps.
