CalendarHighlight + begin/end batch issue

Forum post

Hello Bryntum team,

It seems that there's a glitch when dragging an event whenever the context of the drag becomes invalid.

Follow the config I've used to reproduce the issue:

features : {
        calendarHighlight : {
            calendar : 'event',
        },
    },

Then I am simulating a case where I make the context.valid false:

beforeEventDropFinalize({ context, ...e }) {
            context.valid = false;
            context.eventRecord.eventStore.beginBatch();
            context.eventRecord.eventStore.endBatch();
        }

The issue happens whenever I try to perform a begin/end batch while having the calendarHighlight feature set.

To reproduce the glitch:

Try to move an event to a different timespan (it will jump back to its original position as context.valid is false) Zoom out The event "disappeared". But the truth is that it jumped far away to the right. If I try to move that event again, it will jump back to the original position.
