John,
It shouldn't. There was a spec change and your browser may be caught
between versions. If you insert an existing DOM node into another
portion of the tree, it will first be removed from its existing location
before it appears in the new location. A clone should create a
completely separate copy; however, there may be some issues with data
structures inserted into the DOM that are intended to be single-existence.
