repo.Network.Remotes.Remove does not remove the remote

We have this code below where we remove remote (origin) before adding a new one. From time to time, Add would fail with remote already exists. Is there an issue where remote is not removed when calling repo.Network.Remotes.Remove? Is it a race condition? We doubt it is since rerun the same code still yield remote already exists. Anything we do wrong or can improve? BTW, if we run git remote remove origin command, then it is removed - so repo is not corrupted.

repo.Network.Remotes.Remove(_remoteAlias);

// Configure the remote
remote = repo.Network.Remotes.Add(_remoteAlias, remoteUrl, refSpec);

从 LibGit2SharpRepository.cs 第 234-237 行中引用的 Kudu 代码开始，跟踪后续 Add 之前的 repo.Network.Remotes.Remove 调用。重现报告的 remote-already-exists 行为，然后验证 remote 已被移除，并且可以再次添加而不会失败。
