    Default [Classic 6.2.x 6.5.x] Tree rendering problem if child nodes are lazy loaded

    There is a tree rendering problem since ExtJS 6.2.0 if the child nodes are lazy loaded.
    See this fiddle for demonstration: https://fiddle.sencha.com/#fiddle/243u/.

    Reason is the change in function afterEdit (class Ext.data.TreeStore) introduced in ExtJS 6.2.0. Reverting this change back to the version from ExtJS 6.0.x fixes this issue.

    Temporary override (with unknown side effects):

    PHP Code:
    Ext.define('Ext.overrides.data.TreeStore', {
        
    override'Ext.data.TreeStore',

        
    afterEdit: function(nodemodifiedFieldNames) {
            var 
    me this;

            if (
    me.getRoot() && me.needsLocalFilter()) {
                
    me.onFilterEndUpdate(me.getFilters());
            }

            
    me.callSuper([nodemodifiedFieldNames]);
        }
    });
