title: mouseenter event on background svg elements
body: <p>Is there a way of triggering <code>mouseenter</code> events on SVG elements that are behind other elements? It seems like the top element is catching the event and it is not bubbling up the DOM. </p>
  
  <p>Alternatively, is there a good way of checking if the mouse is over a specific SVG element? </p>
  
  <p>To clarify, I am trying to implement a 'drag &amp; drop'-like functionality where i change the front element depending on the back one. Note that the elements are not nested. </p>
