Esto debería funcionar:

Me sorprendió descubrir que esto no tenía que ver con los cambios recientes en el historial, sino que fue causado por un nuevo `willTransition` añadido en un [commit](https://github.com/discourse/discourse/commit/71bf9ec1b23a38396d92caaa40f2d43ef6f2b548) recientemente fusionado.

Supongo que siempre debemos recordar `return true` en los métodos `willTransition`.
