    Yes, there are no such events but it’s easy to create them by yourself. Here’s my fieldset which extends original one and has requested events:

    Ext.define('MY.fieldset', {
        extend: 'Ext.form.FieldSet',
        alias: 'widget.myfieldset',
        initComponent: function() {
            this.addEvents('beforeexpand', 'beforecollapse');
            this.callParent([arguments]);
        },
        setExpanded: function(expanded){
            var bContinue;
            if (expanded)
                bContinue = this.fireEvent('beforeexpand', this);
            else
                bContinue = this.fireEvent('beforecollapse', this);
            if (bContinue !== false)
                this.callParent([expanded]);
        }
    });
    

    And here is working example.
