Cannot read property 'preload' of undefined

[arishoham]

With nextjs v13.1.7-canary.3, the 'preload' function no longer exists on next/dynamic components with {ssr: false}, causing an error Cannot read property 'preload' of undefined

Setting ssr to true also doesn't seem to be working as expected as the preloaded component still required to wrap the tests inside act/waitFor.

Although not a really clean solution, this can work as a temporary patch (inside the createFactory function):

let c = () => null;

const promiseLoader = loader().then((comp) => {
  c = typeof comp === 'function' ? comp : comp.default || (() => null);
});

mockInitializers.push(() => promiseLoader);

return (props) => c(props);
