Deleting a branch auto-closes any PRs targeting the deleted branch

I have a pull request targeting my default branch from branch A, and I have a PR for branch B targeting branch A.

When I merge the PR for branch A into my default branch and delete branch A on local and remote from the Pull Request description view in VSCode, my PR for branch B targeting branch A is closed and cannot be reopened. I have to create a new PR targeting my default branch from branch B and I lose all history of comments and reviews that were in the original PR for branch B.

When I do the same process in the Github.com web console, the PR for branch B targeting branch A automatically gets updated to target my default branch when I merge and delete branch A.

• Extension version: 0.108.0
• VSCode Version: 1.99.1
• OS: Mac OS Version 15.4 (24E248)
• Repository Clone Configuration (single repository/fork of an upstream repository): single repository
• Github Product (Github.com/Github Enterprise version x.x.x): Github.com

Steps to Reproduce:

1. Create a PR on branch A with a target of default branch
2. Create a PR on branch B with a target of branch A
3. Merge the PR for branch A into default branch
4. Delete branch A on local and remote
5. Observe that PR for branch B is now closed and cannot be reopened
