`TaskCopyPaste` doesn't show nested tasks after paste

[chuckn0rris]

Copy and paste task with children here https://bryntum.com/products/gantt/examples/advanced/ See no child copied. Try the same here https://bryntum.com/products/gantt/docs/api/Gantt/feature/TaskCopyPaste It worked as expected and child nodes pasted.

On copy paste nested tasks the Gantt doesn't show the expander for copied tasks but it appear if I closed and reopened the Gantt Like shown in the attached video you can test using this project " Nested Tasks "
