Encountered the same bug. Here's my override:

Code:
Ext.define('Override.Ext.panel.Table', {
   override: 'Ext.panel.Table',

   applyScrollable: function(scrollable) {
      if (this.view) {
         this.view.setScrollable(scrollable);
      } else {
         this.viewConfig = this.viewConfig || {};
         this.viewConfig.scrollable = scrollable;
      }
      return null;
   }
});
