Routing bug/help

Hi all.

One of my routes that works in 2.1 breaks in 2.2 and 2.3. Wondering if
anyone has thoughts/workarounds.

ActionController::Routing::SEPARATORS << "," unless
ActionController::Routing::SEPARATORS.include?(",")

map.article
":section/:title,:id", :controller=>'articles' , :action=>'show', :requirements
=>{ :id=>/\d{1,}/ }

  def test_route_properly_splits
   opts = { :id =>
"2", :title=>'title_is_foo', :section=>'theSection'}
   assert_routing "theSection/title_is_foo,2", opts
  end

1) Error:
test_route_properly_splits(ArticlesControllerTest):
ActionController::RoutingError: No route matches "/theSection/
title_is_foo,2" with {:method=>:get}
    test/functional/articles_controller_test.rb:33:in
`test_route_properly_splits'

When I try to generate the route from console, I get the following:
"http://whatever/theSection/title_is_foo,:id"

Suggestions?
