Copy-pasting collapsed subprocess does not past child elements correctly

Copying and pasting collapsed subprocess does not paste task inside subprocess

When copy-pasting a collapsed subprocess that contains a task, the task is pasted on top of the collapsed subprocess. However, this appears to be just a visual problem. When downloading and reimporting the .bpmn file everything is fine.

Steps to Reproduce

1. Create expanded subprocess and add at least one child task
2. Collapse the subprocess
3. Copy the sub process
4. Paste the sub process.

Expected Behavior

The child task should be visually hidden.

Environment

• Browser: [e.g. Firefox Developer Edition]
• OS: [ Mac OS X ]
• Library version: [v6.2.0]

As far as I can see, the problem appears to be that the shape.hidden property is not copied.

Thanks for your report and thanks for conducting further investigation.

The place in the source code where this one is missing is probably CopyPaste in diagram-js.

Would you like to contribute a PR? If that is the case we'd need a fix + an accompanying test case (cf. CopyPasteSpec).

I will give it a try.
