We have to reconsider the term <malformed polygon>.
May be <malused polygon opacity property> is better in this case.
The default setting of the opaque property of the templategraphic is
If not altered all new polygons are of the "closed" type.
Setting the opaque property to false for using "open" polygons and to
true for "closed" polygons,
do you still consider this as a bug or a work around?
