Changing OOF type may affect the need for column sets.

Changing from fixed to absolute position may require us to insert a column set. Failing to do this may cause immediate rendering problems, but can also lead to crashes further down the road, because we assume that there's a column set for the object. Be less restrictive about (re-)inserting objects into the flow thread.
