title: Open Layer remove passed line when marker moves
body: <p>I'm working with <strong>open layer</strong> I have stumbled on a problem.</p>
  <p>Here is what am I trying to achieve is to remove passed line, when the marker moves.</p>
  <p>To explain a bit more, check bellow example:</p>
  <p><a href="https://openlayers.org/en/latest/examples/feature-move-animation.html" rel="nofollow noreferrer">https://openlayers.org/en/latest/examples/feature-move-animation.html</a></p>
  <p>When clicking start animation, the marker moves, but <strong>the yellow line</strong> that marker passed by, is stayed, I would like to remove that line behind the marker when the marker moves.</p>
  <p>How can that be done with OpenLayers?</p>
