Bug 16766 – DOM Range doesn't correctly update when modifying contents (Acid3)

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: New Bugs

[Andrew Wellington]

This is related to http://bugs.webkit.org/show_bug.cgi?id=16764 but applies to changing the contents of the range not using the range API, but just directly messing with the DOM that contains the range.

Test 16: FAIL (collapsed is wrong after deletion)

      // test 16: Ranges under mutations: deletion
      var doc = getTestDocument();
      var p = doc.createElement('p');
      p.appendChild(doc.createTextNode("12345"));
      doc.body.appendChild(p);
      var r = doc.createRange();
      r.setEnd(doc.body, 1);
      r.setStart(p.firstChild, 2);
      assert(!r.collapsed, "collapsed is wrong at start");
      assertEquals(r.commonAncestorContainer, doc.body, "commonAncestorContainer is wrong at start");
      assertEquals(r.startContainer, p.firstChild, "startContainer is wrong at start");
      assertEquals(r.startOffset, 2, "startOffset is wrong at start");
      assertEquals(r.endContainer, doc.body, "endContainer is wrong at start");
      assertEquals(r.endOffset, 1, "endOffset is wrong at start");
      doc.body.removeChild(p);
      assert(r.collapsed, "collapsed is wrong after deletion");
      assertEquals(r.commonAncestorContainer, doc.body, "commonAncestorContainer is wrong after deletion");
      assertEquals(r.startContainer, doc.body, "startContainer is wrong after deletion");
      assertEquals(r.startOffset, 0, "startOffset is wrong after deletion");
      assertEquals(r.endContainer, doc.body, "endContainer is wrong after deletion");
      assertEquals(r.endOffset, 0, "endOffset is wrong after deletion");
      return 1;
