Descargo de responsabilidad: Después de intentarlo, esto parece que ya no es un problema porque, al menos para mí, solo funciona en mi instalación de WP 3.9.2. Sin embargo, no se pudo encontrar un rastreador de errores correspondiente.
He reunido un pequeño complemento para probar esto, lo que podría ayudar a alguien. Pero como dije en el descargo de responsabilidad anterior, no pude reproducir el problema en una instalación de wordpress actual. He separado el complemento en cuatro archivos, van juntos en un directorio dentro del directorio del complemento.

- Este es un ejemplo de código un tanto generalizado.
- Debe ajustarse al caso de uso real.
