Describe the Bug

Steps to Reproduce

1. Create an event-subprocess in https://demo.bpmn.io/new

4. Press CTRL-V and click

Expected Behavior

The type of the start event should be the same as in the original event-subprocess.

Environment

• Browser: FF101
• OS: Ubuntu 18.04
• Library version: https://demo.bpmn.io/new on July 11, 2022

Hey, thanks for creating this issue. I've looked into it and it seems to be an issue with ReplaceBehavior. It checks against the rules whether an element should be replaced after it was created. In the case of the start event, it performs the check assuming the process is the parent, not the sub-process. Therefore the start event gets replaced.

We will try and get this fixed soon. 👍🏻

Same issue as camunda/camunda-modeler#2438.

Just tried out this fix 7141624 by @barmac and it appears to solve the issue.
