MVC HandleError attribute not working on Controller

Question

I am experimenting with the relationship between Elmah and MVC's plumbed in exception handling, and am surprised at the outcome of the following code. This is a brand new, straight from project template MVC application, and I have only added Elmah modules and handlers to the web.config. And of the course the 'throw':

[HandleError]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";
        throw new Exception("Just for you Elmah!");
        return View();
    }

Break when error is thrown is set to off, yet the debugger still breaks. When I continue I get a YSOD, and an Elmah error log, but it seems HandleError is doing nothing.

JUST IN I didn't think I had to have custom errors turned on, as I thought that was only for 'my' unhandled errors. I guess MVC is just as much a client of that service as I am.

Check HandleErrorAttribute is added to the GlobalFiltersCollection in the Global.asax.cs

public static void RegisterGlobalFilters(GlobalFiltersCollection filters)
{
  filters.Add(new HandleErrorAttribute());
}

Applying the filter globally is the equivalent of adding the attribute to each action. If I apply it to only one action and it doesn't work, applying it to all actions will only have it not working everywhere.
