[OpenLayers-Dev] Patch to Panel.js

[Matthew Michels]

I haven't gotten around to subscribing to the Trac system yet for OpenLayers.
Will try to do that soon.

We found what appears to be a bug in Panel.js, namely that 'children' appears
to not exist on older (3.0 and earlier) versions of Firefox.  I believe that
'childNodes' is the correct W3C member.  


We made this change to fix the problem:

             }
         }
         this.div.innerHTML = "";

We wanted to report this in case this could be of help to others.

Thanks,
