title: Can't assign submit event type
body: <p>Basically the title. Here is how the code looks:</p>
  <pre><code> const handleSubmit = (e: React.FormEventHandler&lt;HTMLFormElement&gt;) =&gt; {
      // e.preventDefault()
    }
  
  &lt;form onSubmit={handleSubmit}&gt;&lt;/form&gt;
  </code></pre>
  <p>Here is the error in full detail:</p>
  <pre><code>Type '(e: React.FormEventHandler&lt;HTMLFormElement&gt;) =&gt; void' is not assignable to type 'FormEventHandler&lt;HTMLFormElement&gt;'.
    Types of parameters 'e' and 'event' are incompatible.
      Type 'FormEvent&lt;HTMLFormElement&gt;' is not assignable to type 'FormEventHandler&lt;HTMLFormElement&gt;'.
        Type 'FormEvent&lt;HTMLFormElement&gt;' provides no match for the signature '(event: FormEvent&lt;HTMLFormElement&gt;): void'.ts(2322)
  index.d.ts(1380, 9): The expected type comes from property 'onSubmit' which is declared here on type 'DetailedHTMLProps&lt;FormHTMLAttributes&lt;HTMLFormElement&gt;, HTMLFormElement&gt;
  </code></pre>
