Resource interpreted as Document but transferred with MIME type application/zip:

I'm unable to successfully download a file from the server using a Web API get call. The download seems to start but then Chrome throws:

"Resource interpreted as Document but transferred with MIME type application/zip"

Firefox doesn't say that but the download still fails.

What am I doing wrong in the following setup?:

    [HttpGet, Route("api/extractor/downloadresults")]
    public HttpResponseMessage DownloadResultFiles()
    {
        int contentLength = 0;
        this.ResultFiles.ForEach(f => contentLength = contentLength + f.FileSize);

        var streamContent = new PushStreamContent((outputStream, httpContext, transportContent) =>
        {
           ...zip files...
        });

        streamContent.Headers.ContentType = new MediaTypeHeaderValue("application/zip");
        streamContent.Headers.ContentLength = contentLength;
        streamContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        {
            FileName = "result.zip"
        };

        var response = Request.CreateResponse();

        response.StatusCode = HttpStatusCode.OK;
        response.Content = streamContent;
    }

I trigger the download via:

  window.location.href = "api/extractor/downloadresults";

With the resulting headers:
