I see the issue that you described. Actually the problem is in the Sitecore.Shell.Applications.Workbox.WorkboxForm class which represents the Workbox Form.

There are two methods:

    /// <summary>Refreshes the page.</summary>
    protected virtual void Refresh()
    {
      this.Refresh((Dictionary<string, string>) null);
    }

    /// <summary>Refreshes the page.</summary>
    /// <param name="urlArguments">The URL arguments.</param>
    protected void Refresh(Dictionary<string, string> urlArguments)
    {
      UrlString urlString = new UrlString(WebUtil.GetRawUrl());
      urlString["reload"] = "1";
      if (urlArguments != null)
      {
        foreach (KeyValuePair<string, string> urlArgument in urlArguments)
          urlString[urlArgument.Key] = urlArgument.Value;
      }
      Context.ClientPage.ClientResponse.SetLocation(WebUtil.GetFullUrl(urlString.ToString()));
    }

In general, the problem is in the Context.ClientPage.ClientResponse.SetLocation(WebUtil.GetFullUrl(urlString.ToString())) line. And is in WebUtil.GetFullUrl(urlString.ToString()) method particularly. This method always returns the URL with the port extension.

Then, looking at details of GetFullUrl method where we can find that it calls GetServerUrl:

public static string GetFullUrl(string url)
{
  Assert.ArgumentNotNull((object) url, nameof (url));
  return WebUtil.GetFullUrl(url, WebUtil.GetServerUrl());
}

The GetServerUrl method looks like:

public static string GetServerUrl()
{
  return WebUtil.GetServerUrl(false);
}

Where the false, is forcePort parameter, which is always 'false'.

Let's skip a calls chain and have a look at the final view of GetServerUrl method:

public static string GetServerUrl(Uri url, bool forcePort)
{
  if (url == (Uri) null)
    return string.Empty;
  string scheme = url.Scheme;
  string host = url.Host;
  string str1 = url.Port.ToString();
  string str2 = string.Format("{0}://{1}", (object) scheme, (object) host);
  if (forcePort || str1 != "80")
    str2 += string.Format(":{0}", (object) str1);
  return str2;
}

Looking at this method we can see that even forcePort is true, the URL will still include port as it is not equal to 80.

So, it is why you always have the port in your URL.

You can create your CustomWorkboxform class and inherit it from the 'WorkboxForm'. Then try to override protected new void Refresh(Dictionary<string, string> urlArguments) method (using new keyword as this method is not virtual). Then you will have to update Workbox.xml with new CustomWorkboxForm code behind implementation (\sitecore\shell\Applications\Workbox\Workbox.xml). There can be some another difficulties with overlapping other methods. But idea might work!
