Hi, I may have found a bug in Git but I'm not sure if it's intentional or not. I checked out to a new branch to test a PR on my repo, and the PR added a submodule. I init'ed and updated the submodule, and when I was done testing, I went back to my main branch. However, it did not remove the submodule, and produced this message: ``` $ git checkout main warning: unable to rmdir 'glfw': Directory not empty Switched to branch 'main' $ ``` A friend of mine has managed to reproduce this behavior. We believe the expected outcome is to remove the submodule folder, but this does not seem to happen. Is this intentional? Best, Adam Hutchings
