Just guessing here:<div>Maybe the state of a layer changes when the tiles finish loading to something more consistent that can be cloned and maybe the <img> element is in a different state or not even there while it is loading? I seem to remember something like that when I was doing the VideoWMS. Correct me if I'm wrong.</div>

</div>I had thought about this too. But I'm still failing to understand how<br>
cloning can lead to this state. Do you mind elaborating a bit? Thank<br>
you.<br>
