title: background-image style of node not working with SVG images
body: <p>When I set node background-image to a SVG file zoom in/out changes background image. This makes ugly visuals. PNG does not have that problem.</p>
  
  <p>This is a node with SVG background <a href="https://i.stack.imgur.com/yk8H5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yk8H5.png" alt="image initially fine"></a></p>
  
  <p>This is the same node when I zoom in. You can see image is also zoomed in
