Bug Description

    eventsSet: this.handleEvents,
    resources: 'https://fullcalendar.io/api/demo-feeds/resources.json?with-nesting&with-colors',
    events: 'https://fullcalendar.io/api/demo-feeds/events.json?single-day&for-resource-timeline',

function handleEvents(events :EventApi[]) { events.forEach((event:any) => { console.log('handleEvents event.resourceId', event.getResources()) }) refresh chrome may have different result, sometime null ,occasion has value

Thanks, confirmed.

I can see when pressing the "refresh" (reload preview) button on your demo, sometimes getResources() is returning null event though the events still appear in the resources.

I wasn't able to replicate this in the vanilla version so it seems specific to the Vue component.
