title: Focus on first item in Downshift Typeahead
body: <pre><code>downshift version: 5.2.7 
  node version: 12.16.2 
  yarn version:1.22.4
  </code></pre>
  
  <p>Using the following sandbox provided on Downshift JS's website: 
  <a href="https://codesandbox.io/s/simple-downshift-with-getrootprops-example-24s13" rel="nofollow noreferrer">https://codesandbox.io/s/simple-downshift-with-getrootprops-example-24s13</a></p>
  
  <p>I'm attempting to focus on the first item in the typeahead list as I filter with:</p>
  
  <pre><code>items.filter(item =&gt; !inputValue || item.label.toLowerCase().includes(inputValue.toLowerCase()))
  </code></pre>
  
  <p>The filter works, however, I'm unsure how to ensure that the item that most closely matches the input is focused on. I would like the user to be able to type in the input and be able to simply hit the 'enter' key to select the top most filtered item ( or closely matching item ) whilst typing. How would I do so with the Downshift package?</p>
