I don't know all the details in how osmarender deals with relations,
but, I think this is caused because the relation does not have any
tags (besides type=multipolygon).

I have changed that for one of them (304245).  We'll see whether that
makes a difference.

This is the recommended way of tagging anyway.  When a relation is
used to form a feature like a riverbank the tags should go onto the
relation and be removed from the member ways.

Besides, this relation is a chore to work with because it has 365
members.  I would say it should be split where tributaries enter the
main river.
