event.preventDefault() does not work in $routeChangeStart after $route.reload()

[ldvcgllm]

Angular version 1.3.0

Failing code

    $rootScope.$on('$routeChangeStart', function(event, curr, prev) {
        if (...condition1...) {
            event.preventDefault();
            // do something to get condition1 == false
            $route.reload();
        }

        if (...condition2...) {
            event.preventDefault(); // <-- this is not preventing
            // do something to get condition2 == false
            $route.reload();
        }
    });

Issue in source

      reload: function() {
        forceReload = true;
        $rootScope.$evalAsync(function() {
          // Don't support cancellation of a reload for now...
          prepareRoute(); // <-- param is empty
          commitRoute();
        });
      },

...

function prepareRoute($locationEvent) {
  var lastRoute = $route.current;

  preparedRoute = parseRoute();
  preparedRouteIsUpdateOnly = preparedRoute && lastRoute && preparedRoute.$$route === lastRoute.$$route
      && angular.equals(preparedRoute.pathParams, lastRoute.pathParams)
      && !preparedRoute.reloadOnSearch && !forceReload;

  if (!preparedRouteIsUpdateOnly && (lastRoute || preparedRoute)) {
    if ($rootScope.$broadcast('$routeChangeStart', preparedRoute, lastRoute).defaultPrevented) {
      if ($locationEvent) { <-- is undefined
        $locationEvent.preventDefault();
      }
    }
  }
}

@tbosch we should probably check if we need to reload the route after preventDefault, in case it was called during the handler

adding a tag because this is an issue for one of our larger internal teams...

Is it possible to provide a running example of this issue?
Or even better a failing unit test?
