I'm not sure how the context menu in Plasma Active is implemented but if it is 
a normal Window, I am sorry to say that this is a well known and common 
limitation of the X Windowing System: it is impossible to lock the screen 
while a context menu or a normal menu is shown.

Reason: the context menu performs a keyboard grab which means that the screen 
locker cannot get the grab and refuses to lock the screen.
