Unable to push to Azure DevOps repository when project name contains space

I am not able to push to an Azure DevOps repository if the project name contains one ore more spaces. I have tested the exact same code with an Azure DevOps repository that is in a project name without spaces and that works. It looks like the %20 in the URL is being unescaped, which causes Azure DevOps to return a 400 Bad Request. All other operations like fetching work just fine.

Reproduction steps

var repository = new LibGit2Sharp.Repository(LibGit2Sharp.Repository.Clone("https://somegitrepositoryurl", "C:\temp\mytempfolder", new CloneOptions
{
    Checkout = true,
    FetchOptions =
    {
        CredentialsProvider = new SecureUsernamePasswordCredentials
        {
            Username = "SomeUsername",
            Password = SomePasswordInASecureString
        }
    }
}));

var remote = _repository.Network.Remotes.Add("target", "https://dev.azure.com/myorganisation/My%20Project%20With%20Spaces/_git/my-repository");

_repository.Network.Push(remote, _repository.Head.CanonicalName, new PushOptions
{
    CustomHeaders =
    [
        $"Authorization: Basic {Convert.ToBase64String("someusername:somepassword"u8.ToArray())}"
    ]
});

Note that I have first tried using the CredentialsProvider property in PushOptions, but that didn't help. Providing credentials with the custom header works fine in Postman for the same URL.

Expected behavior

Branch is being pushed to Azure DevOps repository.

Actual behavior
