I noticed that we may have missed something here.
Try to run dart2dart with minifier on the following code:
typedef void MyFunction<T extends num>(T arg);

main() {
  MyFunction a;
}

This translates to:
typedef void A<T extends num>(B arg);
main(){A a;}

(somehow T is missed in type arguments, but is renamed in 'arg' type).

This is from test tests/language/function_type_alias_test.dart

Do you want to take a look?

node.visitChildren(this);
probably my last change in ClassNode affects this.
