Description Oriol Brufau 2022-11-24 08:05:01 PST

Run this code:

  var {style} = document.createElement("div");
  style.markerStart = "url(start)";
  style.markerMid = "url(mid)";
  style.markerEnd = "url(end)";
  style.marker; // "url(\"start\")"
  style.marker += "";
  [style.markerStart, style.markerMid, style.markerEnd]; // ["url(\"start\")", "url(\"start\")", "url(\"start\")"]

style.marker should be serialized as empty string when the longhands have different values.
