Run in console.

scheduler.on({
    beforeEventSave() { console.log('beforeEventSave') }
})

Edit an event, save, confirm. See no logs in console. Expect beforeEventSave to be fired.
Create a non-repeating event. Save. See beforeEventSave is fired.
Edit it again. Save. See beforeEventSave is fired.
