Error 400 when cloning TFS Git repo using Visual Studio 2017

In Visual Studio 2017, when I attempt to connect to an existing on-premise TFS 2015 team project, and attempt to clone an existing Git repo using Team Explorer (by clicking the Clone button after highlighting the the repo name in the Connect to a Project modal), I get error message saying

Git failed with a fatal error. fatal: unable to access 'https://servername:8080/tfs/Team Projects Collection/ProjectName/_git/RepoName/': The requested URL returned error: 400

I also get this error showing up in my output window.

UPDATE: It does appear that Microsoft has fixed this issue in an update to Visual Studio 2017. Most likely, Update 3 as mentioned in comment below. If you're not using at least Update 3, this answer may pertain to you still.

This is primarily because Visual Studio 2017 is mishandling spaces in the Team Project Collection name. It does not encode them to use %20 for spaces. Here's steps to work around.

Click Cancel button to close the "Connect to a Project" window.

In Team Explorer, underneath the Clone Repository section, notice how the top box does have spaces in the URL. Cancel the clone by clicking the Cancel link. Do this, because you'll find that you cannot edit the Clone Repository inputs.

Then, click the Clone Repository link in the Project section of the Team Explorer window.

You'll notice the Clone Repository section will reappear, but now will not be editable. Notice that the first/top input box has replaced any spaces in the URL with %20. Ensure that you're second box, which maps a local path to download your source to, is accurate. Click Clone button, and it should work.
