Cannot change the default base branch `main` (GraphQL: Cannot change the base branch because the pull request is part of a stack. (updatePullRequest))

[LeonLH928]

This feature could be better for code management if it can be used for projects with multiple environments since I cannot change the default base branch main to other branches (like staging, or to break a branch into many features and merge into it for better testing)

I have tried the following

# In your local repo
gh pr edit --base <your-parent-branch>

And I got

GraphQL: Cannot change the base branch because the pull request is part of a stack. (updatePullRequest)

I would love an update or explanation for this
