emitting light while in shelf

I noticed that torches don't emit light while in a shelf.

**Describe the solution you'd like**
I request that light-emitting items in your hands, also emit lights in a shelf.

**Describe alternatives you've considered**
I don't know but, I think you have this implemented with item frames? Not sure tough.

**Additional context**
Add any other context or screenshots about the feature request here.
