Assembly, transparent part(s) in assembly, edit part, lose transparency, why?

Irritated at why part(s) set to transparent in an assembly become solid automatically when you choose to edit a part from within the assembly file. SW 2013 SP5.0, and every previous year or SP that I've used that has been installed onto my computers. Is there a setting for this that I'm unaware of or just how it is for the time being?
