'dataSelected' event is not fired in case if SelectionManager.Select() does not have results

Hello.
May be this is not a real issue, but feature. I have web app (Angular 4) with PowerBI embedded report (this report uses custom visual). I receive this event in my app in case if SelectionManager.Select() returns array of selected items. But in case of second click on the same item SelectionManager.Select() returns an empty array and this event is absent.
In any case I'd like to receive this event even with empty data in my app.
My workaround is:

this.report.on('dataSelected', (event) => {
    console.log('dataSelected: ', event);
});

Best regards.
