Call to /request_token after canceling a request fails with HTTP 401 because oauth_token is already set.

Description:

Call to /request_token after canceling a request fails with an HTTP error 401 because credential.oauth_token is already set and is passed to the headers parameters.
I am trying to verify that we can correctly cancel a login attempt to Garmin made with our view controller that implements OAuthWebViewController.
We are canceling the login attempt like this:

var service: OAuthSwift?
private func cancelFlow() {
    service?.cancel()
    dismissWebViewController()
}

But if we try to call service.authorize again, the call fails without opening our custom OAuthWebViewController with a 401 unauthorized error, and the difference is that in the second call the oauth_token parameter is set.

Are we canceling the request the wrong way? Is Garmin supposed to check oauth_token? Is oauth_token supposed to be still set after canceling a request?
