[UNKNOWN][3.0+] CheckItem fires beforecheckchange for initial value

[Condor]

CheckItem fires a beforecheckchange event when the item is initially checked.

Example:

new Ext.Button({
    text: 'Click me',
    menu: [{
        text: 'Item',
        checked: true,
        listeners: {
            beforecheckchange: function(){
                console.log('Don't call me');
            }
        }
    }],
    renderTo: Ext.getBody()
});

Suggested fix:

Ext.override(Ext.menu.CheckItem, {
    setChecked : function(state, suppressEvent){
        if(this.checked != state &&
            (suppressEvent === true || this.fireEvent("beforecheckchange", this, state) !== false)){
            if(this.container){
                this.container[state ? "addClass" : "removeClass"]("x-menu-item-checked");
            }
            this.checked = state;
            if(suppressEvent !== true){
                this.fireEvent("checkchange", this, state);
            }
        }
    }
});
