Crash when dragging events between two schedulers

Hello Bryntum Team,

I have a problem with configuring Bryntum dragging between schedulers using https://bryntum.com/products/scheduler/examples/drag-between-schedulers/ as an example. But after drag ends it throws error in console:

ERROR Error: Uncaught (in promise): TypeError: record.instanceMeta is not a function

After some debugging it looks like isInTimeAxis function gets record's id as value instead of reference to dragged record and this is done in:

// Pro Engine does not seem to handle having the event already in place on the copied assignment,
// replacing it with id to have events bucket properly set up on commit
if (newAssignment.event) {
  newAssignment.event = newAssignment.event.id;
  newAssignment.resource = newAssignment.resource.id;
}

Not sure if i'm doing something wrong?
Also here is drag configuration:

eventDrag: {
	showTooltip: false,
	constrainDragToTimeSlot: true,
	constrainDragToTimeline: false
}

To reproduce:

1. unzip drag-between-schedulers.zip to SchedulerPro/examples and then run it.
2. drag an event from the bottom scheduler to the top one
3. it crashes:

Note: The content of app.js is copy & paste from Scheduler examples adjusted to use SchedulerPro.
