The behaviour is as documented.  I should have done something wrong
yesterday.

Hmm.... Losing something to gain some thing else doesn't seem good to
me.

I cursorily looked at cperl-mode.  My gut feeling is that which-function
decides the box it is in by looking at the markers that is returned.  So
we may have to examine what value goes in to the marker.  

My recommendation would be to put the patch on hold.
