Steps to reproduce:
- Create an item on a DMX track and write some DMX data into it
- Select the item and click “copy”
- Move playback to another position and with the same track selected, click “paste”
- A DMX item with the same length as the copied item is created at the playback position
- The pasted DMX item contains no DMX data
Expected behaviour:
- The pasted item contains the same DMX data as the copied item
