Even some more stylo derived errors

Input C/C++ Header

template <class T> class RefPtr { T a; };
template <class T> class nsMainThreadPtrHolder { T a; };
template <class T> class nsMainThreadPtrHandle {
  RefPtr<nsMainThreadPtrHolder<T>> mPtr;
};

Bindgen Invokation

Complicated, will get back with a minimal invokation in a bit.

    #[derive(Debug, Copy, Clone)]
    pub struct nsMainThreadPtrHandle {
        pub mPtr: root::RefPtr<root::nsMainThreadPtrHolder<T>>,
    }
}

Which results in compilation errors like

error[E0412]: cannot find type `T` in this scope
  --> stylo_structs.rs:30:60
   |
30 |         pub mPtr: root::RefPtr<root::nsMainThreadPtrHolder<T>>,
   |                                                            ^ not found in this scope

Expected Results

Some compilation errors from the raw-line insertions, but all type parameters that get referenced should exist.
