after split, the left part grid header may disappear

Suite and Optimus Suite 5
#1

e.g
if mygrid only has 3 columns, then

mygrid.splitAt(2);
mygrid.setColumnHidden(2, true);

then the right part grid will hide, then the left part grid’s header will disappear, because
in

this.setSizes=function(){
            		if (this._notresize) return;
.....
                    this._fake.hdrBox.style.height=this.hdrBox.style.height;
.....
            }

in above code , after right part hidden,this.hdrBox.style.height = 0px, so this._fake.hdrBox.style.height = 0px too, so the left part’s header will hidden.

and then resize the grid will have other problem.

thanks!
