Steps to reproduce the behavior: Using Safari or Chrome on MacOS.

1. Login to playground via https://app.gitstream.cm/playground
2. Run the default file. The .cm automation file

   
   # -*- mode: yaml -*-
   # This example configuration for provides basic automations to get started with gitStream.
   # View the gitStream quickstart for more examples: https://docs.gitstream.cm/examples/
   manifest:
