aliased crafting materials appears not to be handled properly

[fluxionary]

for example, homedecor defines the following recipe:

-- homedecor.materials.slab_wood = "stairs:slab_wood"

minetest.register_craft( {
        output = "homedecor:bench_large_2_left",
        recipe = {
                        { "homedecor:shutter_oak", "homedecor:shutter_oak", "homedecor:shutter_oak" },
                        { "group:wood", "group:wood", "group:wood" },
                        { homedecor.materials.slab_wood, "", homedecor.materials.slab_wood }
        },
})

a PR i've been writing for moreblocks (https://github.com/minetest-mods/moreblocks/pull/191) aliases stairs:slab_wood to default:slab_wood_8.

the result is that the wooden bench is still craftable, but doesn't appear in the list of recipes that unified_inventory lists:

then again, homedecor:shutter_oak is aliased to homedecor:shutter and homedecor:bench_large_2_left is aliased to homedecor:bench_large_2, and i'm uncertain what's different about the aliases in the case of the slabs

figured this out, not a problem w/ unified_inventory. i was setting the not_in_craft_guide group.
