Updating a Workflow While It's Running Spawns Multiple Workflows

[b-erdem]

Describe the bug
We are using Argo Events to trigger our Argo Workflows. Recently we noticed that when you update an existing workflow while it's running, it starts new workflows without getting an event.

To Reproduce
Steps to reproduce the behavior:

1. Create a workflow with a trigger
2. Trigger it.
3. Update workflow while it's running.
4. Check Argo Workflows UI and you'll see it runs a few more(it depends).
5. You might need to do this a few times to see it.

Expected behavior

When you update a workflow while it's running shouldn't spawn new runs.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• Kubernetes: v1.27.4+k3s1
• Argo: v3.4.11
• Argo Events: v1.7.6

Additional context
I tried to reproduce this using only Argo Workflows but couldn't reproduce it. So I thought it's probably related to Argo Events. That's why I opened the issue here. Please let me know if I should do otherwise.
