Solution

  • Try to use this overrride:

        Ext.define('Ext.list.Tree',{
        override:'Ext.list.Tree',
        privates:{
            onMouseOver: function (e) {
                var comp = Ext.Component.fromElement(e.getTarget());

                if (comp.isTreeListItem){ comp.expand()}

                this.setOverItem(comp && comp.isTreeListItem && comp);
            }
        }
    });
