API versioning with header doesn't work for APIs with CORS policies.
We have enabled versioning of APIs using a header 'api-verion'.
We also have enabled CORS policies on the API.
The problem that we have is when a CORS pre-flight request (OPTIONS) is sent to API by browser the required `api-Version` header is not present and thus a 404 is returned from API-M and we receive a CORS Failure in the browser.
We have the same issue.
