MultiAssignments with ResourceIds clone issue

[Sisco21]

Hello,

I'm trying to use MultiAssignments with auto commit on the eventStore and this.schedulerConfig.features.eventCopyPaste = { copyPasteAction: 'assign' }; on Scheduler product.

The expected behavior will be on the OnCommit, to have in the resourceIds only the one i copy to. But i've got all the resourceids of the source model.

You can reproduce it on the MultiAssignments exemple and copy the attached code.
