showHeaderContextMenu not working for headerSpans

[wallytax]

If I disable the header's context menu in a ListGrid (showHeaderContextMenu: false) it works for all column headers, but not for a header span, which still shows the context menu. Is this a bug or is there another thing I can do to disable this behavior?

I'm using SmartClient 10.0p2015-11-20 Pro on latest Chrome for Mac.

A fix for this seems to be:

  getHeaderSpanContextMenuItems: function() {
    return false;
  }
