Fixed the clippy::needless_borrow, but now the wasm build fails:

error[E0308]: mismatched types

                  found struct `std::cell::RefMut<'_, winit::window::Window>`

The difference seems to be:

        #[cfg(target_arch = "wasm32")]
        let winit_window = winit_window.borrow_mut();

        #[cfg(not(target_arch = "wasm32"))]
        let winit_window = glutin_window.window();
