title: Emotion Styled Components not autocompleting in WebStorm
body: <p>I'm using <code>@emotion/styled</code> in WebStorm and there's no Intellisense (or whatever it's called in WebStorm) for autocomplete within my style object. Typescript does appear to be checking to some degree:</p>
  
  <pre class="lang-js prettyprint-override"><code>const StepTimer = styled.button({
    borderRadius: 50,
    height: '30px',
    blorg: 3, // does not give a TS error for unknown key
    display: 1 // gives a TS error for incorrect value type
  })
  </code></pre>
  
  <p>VSCode on the same computer gives autocomplete inside the object, although not for values (e.g., I don't get options for <code>display</code>'s value like <code>block, inline,</code> etc.)</p>
  
  <p>Is there some setting I have wrong? I'm on a Mac.</p>
