Not possible to hide delete button on the event editor

In the documentation there is an example here Scheduler.feature.EventEdit#config-editorConfig

const scheduler = new Scheduler({
    features : {
        eventEdit : {
            editorConfig : {
                bbar : {
                    items : {
                        deleteButton : null
                    }
                }
            }
        }
    }
})

This approach works with the scheduler, but not with the calendar. A crash occurs when opening the editor dialogue, and this can be readily reproduced on the basic calendar demo by adding the same eventEdit section within features.

I also tried using deleteButton: { hidden: true } and that made no diffference.

As a workaround we hook beforeEventEditShow and call deleteButton.hide()
