title: Click through PNG image - only if clicked coordinate is transparent
body: <p>I have an image like this:</p>
  
  <p><a href="https://i.stack.imgur.com/Ab6aW.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/Ab6aW.jpg" alt="enter image description here"></a></p>
  
  <p>I want it so that when I click the transparent parts, the click should go through to the underlying element, but when I click a non-transparent part, this image element should get the click.</p>
  
  <p>Is this even possible?</p>
