  [IFC][Partial layout] Reuse previously computed damage point on append
https://bugs.webkit.org/show_bug.cgi?id=261384

Reviewed by Antti Koivisto.

Subsequent append type of mutations always produce the same (last line) damage entry point.

e.g.
  container.appendChild(textNode);
  container.appendChild(brElement);
  document.body.offsetHeight;
