the last change of StdGridLayoutImpl.js make WHBoxLayout with AlignLeft flag has different result than 3.1.9.

and sometimes make javascript crash. see the attachment files.

the only change:

3.1.9

     if (!shallow) {
       p = ch.parentNode;
       w = p.offsetWidth - self.marginH(ch);
       if (self.getColumn(col)) {
     var cw = self.getColumn(col).style.width, cwl = cw.length;
     if (cwl > 0 && cw[cwl-1] == '%') {
       ch.style.position = 'absolute';
       ch.style.width = w+'px';
     }
       }
     }

3.1.10

     if (!shallow) {
       p = ch.parentNode;
       w = p.offsetWidth - self.marginH(ch);

       if (p.className == 'Wt-chwrap') {
     if (!WT.isIE) {
       ch.style.position = 'relative';
       ch = ch.firstChild;
     }
     ch.style.width = w + 'px';
     ch.style.position = 'absolute';
       }
     }

ch.style.width = w + 'px';

sometimes w<0 make javascript crash.

when i restore the StdGridLayoutImpl.min.js of version 3.1.9

the result is correct, and crash never found.
