Description Simon Fraser (smfr) 2021-01-23 10:41:09 PST 
https://codepen.io/cobra_winfrey/pen/WNGJPXm looks very wrong in WebKit
Comment 1 Simon Fraser (smfr) 2021-01-23 10:43:25 PST 
Content has:

    <filter id='filter1'>
      <feturbulence basefrequency='0.005 0.005' id='frequency1' numoctaves='1' result='noise' seed='1' type='fractalNoise'></feturbulence>
      <fedisplacementmap id='displacement1' in2='fractalNoise' in='SourceGraphic' scale='0'></fedisplacementmap>
    </filter>

and we fail to find the "in2" input for the <fedisplacementmap>
