IsSpecial() doesn't work

create type Foo {
representation Foo { AsString : String },
special Bar Foo("Bar")
};

create table Baz in System.Temp {
Foo : Foo
};

insert table {
row { Foo("Hallo") Foo },
row { FooBar() Foo }
} into Baz;

select Foo("Hallo"); // Hallo
select FooBar(); // Bar
select Foo("Hello").IsSpecial(); // False
select Foo("Bar").IsSpecial(); // True
select Foo("Bar").IsBar(); // True
select FooBar().IsSpecial(); // True
select FooBar().IsBar(); // True
select Baz; // Bar, Hallo
select Baz where Foo = Foo("Bar"); // Bar
select Baz where Foo = FooBar(); // Bar
select Baz where Foo.IsSpecial(); // fail
select Baz where Foo.IsBar(); // fail

/* This works when running in-process, but when running against the service, the last two queries fail with the following error message:
