    Turn off the animation effects can resolve the issue.

    Is this resolved, or a workaround and it still needs attention?

    You are right, it still needs attention. because the problem still remains, turn off the dynamic effects, just a way to avoid the error occurred.

    There's too many missing parts in your test case to run it directly, so I tried to simulate it and I can't reproduce it with 4.1.1. Please post a test case that I can run locally that demonstrates the issue.

    My sample:

    Code:
    Ext.define('MyModel', {
        extend: 'Ext.data.Model',
        fields: ['name']
    });
    
    Ext.require('*');
    
    Ext.onReady(function() {
        var store = Ext.create('Ext.data.Store', {
            model: MyModel,
            data: [{
                name: 'Item 1'
            }]
        });
        
        Ext.create('Ext.container.Viewport', {
            layout: 'fit',
            items: {
                xtype: 'tabpanel',
                items: [{
                    title: 'A tab',
                    layout: 'border',
                    items: [{
                        title: 'Center',
                        region: 'center',
                        xtype: 'gridpanel',
                        store: store,
                        columns: [{
                            dataIndex: 'name',
                            text: 'Name'
                        }]
                    }, {
                        title: 'South',
                        region: 'south',
                        xtype: 'gridpanel',
                        store: store,
                        columns: [{
                            dataIndex: 'name',
                            text: 'Name'
                        }],
                        height: 200,
                        collapsible: true,
                        collapsed: true,
                        split: true
                    }]
                }]
            }    
        });
    });
