title: Make tooltip display over modal in react-vega-lite
body: <p>I'm working on a react project that uses the <code>react-vega-lite</code> and <code>vega-tooltip</code> packages, making a VegaLite component where </p>
  
  <pre><code>tooltip={new Handler().call}
  </code></pre>
  
  <p>This works in getting a tooltip to display, however my table is in a modal and the tooltip is displayed behind. </p>

  <p>Does anyone know how I can access the css for the tooltip and set it to important?</p>
  
  <p>Thanks!</p>
