Bug with TaskCopyPaste and CellCopyPaste both active

Hi, While testing the cell selection feature, we encountered a few bugs that we'd like to report. All of these issues can be reproduced in the demo: https://bryntum.com/products/gantt/examples/cellselection/

3. Copy-Paste Feature Issue The most critical issue we encountered was with the copy-paste functionality. When enabling both cell and task copy-paste features like this:

cellCopyPaste: true,
taskCopyPaste: true,

The issue occurs when copying and pasting a task, then pasting to a cell, and finally pasting another task. The new task created at the end is empty, missing all information. You can see the behavior in this video:

I hope this helps clarify the problem. We realize it's a bit tricky to reproduce.

Thank you, Luca
