Never insert <object> lazily in DOMLazyTree

#6629

I'm not sure about performance implications or if this might apply to some other node type (I doubt it).

For posterity, I'm unable to update the PR for some reason, but the actual code is:

function queueChild(parentTree, childTree) {
  // Flash Player (and perhaps <object> in general) is created immediately
  // upon inserting into the DOM, so <param> children will not exist yet.
  // This only appends the immediate children right away, but <param> must not
  // be nested so it's good enough.
  if (enableLazy &&
      !(parentTree.node.nodeName &&
        parentTree.node.nodeName.toLowerCase() === 'object')) {
    parentTree.children.push(childTree);
  } else {
    parentTree.node.appendChild(childTree.node);
  }
}

Bad fix, this doesn't actually work with nesting inside the object...
