Ahh I see, the json envelope is stale after the deployment. Good news is, it doesn't make any active changes to the container app, which makes sense why it's not detecting unsaved changes. I personally think it's not worth the effort to try to design around this since a user can simply close and reopen the json after the new deployment has been made. I'll throw in backlog candidates to see if people want this enhancement.
