[4.1B3] Scrolling a buffered grid is broken

[mankz]

These 2 methods cannot have been run ever.

onLockedViewScroll: function() {
        var me = this,
            lockedView = me.lockedGrid.getView(),
            normalView = me.normalGrid.getView(),
            normalTable,
            lockedTable;

        normalView.el.dom.scrollTop = lockedView.el.dom.scrollTop;

        
        if (me.store.buffered) {
            lockedTable = lockedView.child('table', true);
            normalTable = normalView.child('table', true);
            normalTable.dom.style.top = lockedTable.dom.style.top;
        }
    },
    
    onNormalViewScroll: function() {
        var me = this,
            lockedView = me.lockedGrid.getView(),
            normalView = me.normalGrid.getView(),
            normalTable,
            lockedTable;

        lockedView.el.dom.scrollTop = normalView.el.dom.scrollTop;

        
        if (me.store.buffered) {
            lockedTable = lockedView.child('table', true);
            normalTable = normalView.child('table', true);
            lockedTable.dom.style.top = normalTable.dom.style.top;
        }
    },

Bold rows above should be lockedView.el.child. That gives us a DOM node, so row under should not do ".dom."

We will look into it.
