Genau das passiert leider nicht. Vielleicht gibt es da einen Unterschied zwischen den PHP oder Joomla Versionen?
Ich habe die Variable umgeschrieben, sodass nun ein (für mein System) passender Pfad rauskommt - jetzt funktioniert es.
Ist abstrakt schwer zu beantworten, ggf mal den Content-Disposition Header von online zu attachment umstellen.
Bei mir funktioniert es bei Joomla Ver 3.X sowie Joomla 5.x, nachdem ich aber mit verschiedenen Hoster arbeite, hat es anfänglich nicht gefunzt.
Der Grund war, dass es jeweils nginx Server waren, keine Apache, nginx verarbeitet offenbar kein .htaccess und findet deswegen natürlich das Script nicht - also alles paletti, vielleicht sind diese Angaben für einige User interessant

Ich kann da auch nur raten; eigentlich sollte die URL in einem str_replace entfernt werden, sodass nur die releative URL übrig bleiben sollte:
