item lighting in shadow on vulcanus

[AqueousOrca3148]

i don't think this is a particularly important issue, but its probably the first one i've ever seen in my 2000 hours, so i got excited.

i was messing around with quality on vulcanus when i noticed a weird looking piece of steel, however after a while, it would be apparent it wasn't a fluke, and happens repeatedly.

^testing - recyclers are stacked at 2 high


steps to reproduce
- have belt stacking research at 2, i haven't tested at higher amounts
- place foundry or entity with tall shadow
- stack items onto belt at 2 high
- 2 high items will not be darkened by the shadow

this should reproduce the lighting bug in the pictures
