[mkgmap-dev] Problem with aeroway=aerodrome as a relation

Could somehow mkgmap have an issue with aeroway=aerodrome as a relation? (instead a simple closed way) For example, this airport http://www.openstreetmap.org/way/90834745 have its internal grasses properly represented like here: http://cocardl.com.br/pv/viracopos.jpg On the other hand, this airport http://www.openstreetmap.org/relation/3896781 seems to overlap every internal feature (like grasses): http://cocardl.com.br/pv/galeao.jpg Is mkgmap giving different treatments for aeroway=aerodrome as a closed way and as a relation?
