Editor "multiselect" can not cancel values by ESC

I use element type=“multiselect” (with suggest “checksuggest”) into view property. When I press key Esc (to cancel edit and not save change), the popup is hiding, but event “onAfterEditStop” is not called. Then I click on any place (eg other property element), event triggered with params old and new values (of element multiselect) and ignoreUpdate=undefined. And then new value is applyed.
How to undo user selected values?
I am trying to handle the onKeyPress event and call the editCancel() method of the view “property”. This does not work.
My example:

{
    view: 'property',
    id: 'cell_props',
    complexData: true,
    elements: [
        {
            label: 'Date from',
            type: 'date',
            id: 'opt.dateFrom',
            value: '',
            format:  webix.Date.dateToStr('%d.%m.%Y'),
            suggest: {
                type: 'calendar',
                body: {
                    icons: true,
                    on: {
                        onDateClear: function() {this.hide();}
                    }
                }
            }
        },
        {
            label: 'Date to',
            type: 'date',
            id: 'opt.dateTo',
            format:  webix.Date.dateToStr('%d.%m.%Y'),
            suggest: {
                type: 'calendar',
                body: {
                    icons: true,
                    on: {
                        onDateClear: function() {this.hide();}
                    }
                }
            }
        },
        { 
            label: 'Regions',
            type: 'multiselect',
            options: [{id:'01', value: 'Region 01'},
                {id:'02', value: 'Region 02'},
                {id:'03', value: 'Region 03'},
                {id:'04', value: 'Region 04'},
                {id:'05', value: 'Region 05'},
                {id:'06', value: 'Region 06'},
                {id:'07', value: 'Region 07'},
                {id:'08', value: 'Region 08'},
                {id:'09', value: 'Region 09'},
                {id:'10', value: 'Region 10'}
            ],
            id: 'opt.regions',
            width: 300,
            suggest: {
                view: 'checksuggest',
                selectAll: true,
                button: true,
                body: {
                    template: '#id# - #value#',
                    yCount: 15
                }
            }
        }
    ],
    on:{
        onBeforeEditStart: function(id){
            return true;
        },
        onAfterEditStop(state, editor, ignoreUpdate) {
            console.log(ignoreUpdate);
            console.log(state);
            if (state.value.valueOf()!=state.old.valueOf()) {
                console.log('save');
            }
        }
    }
}
