canSubmit not updated on first submission failed

Describe the bug

[UPDATE] this also happen when the server-side validation failed, submit with value "9"(valid in client but not server), same issue happen.

I'm not sure if this is a bug or intented, but If a form-level error is returned from server action in nextjs, the canSubmit property is not updated in the first submission, but it works when you submit the same form again.

return the following from server action to simulate error during processing the form

  return {
    errors: ['Server validation failed'],
    errorMap: { onServer: 'Server validation failed' },
    values: formData,
  }

Steps to reproduce

1. type in a number > 12 (to fulfill the validation), e.g. 99
2. click submit, you will see the "Server validation failed" message but the submit button is still clickable which canSubmit is true if you print out the state
3. click the submit again, canSubmit become false so the button is disabled

Expected behavior

I expected canSubmit to become false at the first submit failed.

No response

Start by running the linked minimal reproducible example or CodeSandbox with @tanstack/react-form and @tanstack/form-core at the reported versions. Reproduce a server-side validation failure on the first submission and trace the form state update; done means canSubmit becomes false immediately after that failed submission.
