• I have run fig restart and replicated the issue again

Operating system

macOS 13.3.1 (22E772610a)

Expected behaviour

After deleting my local and remote git branches, I expect the branch names don't show up in the suggestions when I type git checkout

Actual behaviour

When I delete my local and remote git branches, the branch names still showing up in the suggestions when I type git checkout

Steps to reproduce

Scenario 1

1. Delete a local branch git branch -D sample_branch
2. Type git checkout and you will see sample_branch is in the suggestion list when it shouldn't

Scenario 2

1. Delete a remote branch git push --delete origin sample_branch
2. Update your local git environment with remote git fetch --prune
3. Type git checkout and you will see sample_branch is in the suggestion list when it shouldn't

Hmm this sounds like an issue with the suggestion caching. This should be solved by modifying the git.ts completion spec and changing the generator caching policy.
