Observatory strong mode fix: Fix a callback parameter type using an explicit downcast.

For brevity we explicitly downcast the parameter type (using "as")
rather than implicitly downcasting it (by assigning to a fresh
variable).  Since this is test code, I'm not concerned about the
performance penalty of the explicit downcast.
