<Form/> cannot submitted via ‘action’ property

I'm currently experimenting with a login form implemented using rc-field-form at its core that interacts with an OAuth2/OIDC implementation that expects a traditional server side rendered app for the login form. For this reason, I want to not attach an onFinish() callback to the form, but instead submit it via the native <form> submit mechanism, by setting the action property on the form, like so:

<Form name="test-form" action="https://httpstat.us/200" method="post">
  <Field name="test-field">
    <input placeholder="test field" value={""}/>
  </Field>
  <button type="submit" value={"submit"}>
    Submit
  </button>
</Form>

Since FormProps transitively extends React.FormHTMLAttributes I was expecting this to work, but of course it doesn't because here the event propagation of the submit click is stopped in favour of delegating processing to the form instance. I think rc-field-form's behaviour would be less surprising if event propagation were only stopped if:

• Form validation fails
• An on finish callback is actually attached to the form.

Of course, the alternative would be to omit action (and probably method) from FormProps, though that hardly seems satisfactory to me.

A demonstrator reproducing the bug can be found here: https://github.com/ngrewe/rc-field-form-bug

Start in src/Form.tsx at the submit event handling around lines 164–165, then run the linked demonstrator repository to reproduce the failed native submission. The fix should allow a form with action and method to submit through the native mechanism while preserving validation behavior and onFinish handling.
