Bug description

The current TimeGridEvent component is rendered with a key of evt_${index}. When trying to maintain rendering state when attached to a child of this component, unexpected behavior occurs if an event is is removed or added from the event array.

Expected Behavior

Id expect that events can be uniquely identified beyond the index element of the array.

Actual Behavior

Events are key'd simply by array index.
