Although the collapsed property is correctly stored in localstore.rdf, it seems not to apply at startup. The problem might be that - as the toolbar itself is created at startup from data from localstore.rdf - it might not yet exist when the persistent attributes are applied.

Expected Results: It should stay hidden.
