title: How to toggle popup in react-leaflet on mouse hover
body: <p>I tried everything I found on google and I can't figure out how to trigger the popup.       </p>
  
  <pre><code>&lt;Marker
    position={this.props.position}
    onMouseOver={() =&gt; { openPopup() }}
    onMouseOut={() =&gt; { closePopup() }}
  &gt;
    &lt;Popup&gt;
       "HI"
    &lt;/Popup&gt;
  &lt;/Marker&gt;
  </code></pre>
  
  <p>Note: I know I can't trigger the function openPopup there its just to show where I want to implement the trigger function to toggle the popup on mouse hover.</p>
  
  <p>Can someone please help, Thanks.</p>
