Soul torches and pumpkin doesn't create Soul Jack-o-lantern

Description:

When I was playing, I tried to make a soul jack-o-lantern using a soul torch. Soul torches make soul lanterns, so with that logic I can create a jack-o-lantern. It failed. I can tell the devs just forget jack-o-lantern used torches.

How to reproduce:

Grab a carved pumpkin and torches, make a jack-o-lantern.  Now so the same with a soul torches.

What is expected:

A soul jack-o-lantern, but nothing happened.
