title: ReactTooltip.hide doesn't hide tooltip instantly
body: <p>I'm trying to create a tooltip using <code>react-tooltip</code> with a close button.
  According to the <a href="https://github.com/wwayne/react-tooltip#reacttooltiphidetarget" rel="nofollow noreferrer">documentation</a>, I need to use <code>ReactTooltip.hide</code> but it doesn't seem to work. It hides the tooltip only if I'm moving the cursor out of the tooltip, but not instantly.</p>
  <p>Using React 17.0.2, react-tooltip 4.2.21.</p>
  <p>Here's a quick CodeSandbox example to see my issue: <a href="https://codesandbox.io/s/hidden-star-er2u66" rel="nofollow noreferrer">https://codesandbox.io/s/hidden-star-er2u66</a></p>
