title: Material UI Autocomponent: Passing style to inputProp={} creates error
body: <p>Passing style to inputProp={} inside an Material UI Autocomplete would create an &quot;useAutocomplete.js:919 Uncaught TypeError: Cannot read property 'focus' of null&quot; error.
  Here is the example code:</p>
  <pre><code>renderInput={params =&gt; (
            &lt;div&gt;
              &lt;TextField
                multiline={false}
                classes={{
                  root: classes.textField
                }}
                {...params}
                variant=&quot;outlined&quot;
                placeholder=&quot;Search&quot;
                inputProps={{ classes: { root: classes.text } }}
              /&gt;
            &lt;/div&gt;
  )}
  </code></pre>
  <p>I do not really understand the Problem, are there any suggestions?</p>
