[React 19] When submitting a form action multiple times, requestFormReset throws the TypeError 'Cannot read null property (reading 'queue')'.

Related Previous Issues: #30041
Related Previous PR: #30365

There was already a PR raised, but I wrote a PR to be more specific and prevent type errors.

When passing an asynchronous function to a

action, if you pass that action again before receiving the response, the stateHook.next value will be null in the ensureFormComponentIsStateful function running inside the requestFormReset function, resulting in a type error. To prevent this problem, I modified the ensureFormComponentIsStateful function to maintain the current statefull state if the stateHook.next value is null.

Test Code

function App() {
  const formAction = async () => {
    await new Promise((resolve) => setTimeout(resolve, 3000));
  };
  return (
    <form action={formAction}>
      <input type="text" name="name" />
      <input type="submit" />
    </form>
  );
}
export default App;

Test Step

1. Enter any text in input text.
2. Submit.
3. Submit multiple times within 3 seconds (setTimeout time).
   (usually after 2-3 seconds, just before the response comes)
