issues with 2.4.0

[NizarBlond]

1. The slideButton is not clickable, you have to manually slide to get to the menu!

I found a workaround for this using openContainer/closeContainer methods.

2. setItems/addItems are broken.

I want to add items according to certain condition (e.g. logged user is admin).
Adding the items in config: {items: [..]} works, but it doesn't work if I add them using setItems/addItems renders a messed up view.

e.g.

The following renders a messed up design.

 initialize: function() {
    this.callParent(arguments);
    this.setItems([{...}]);

}

While adding same items in the following is ok:

config: {
items: [...]
}

Any workarounds? I badly wanna use this feature!
