I have layered icons with tier pips, and to avoid displaying the tier pips in-world on belts and on the ground, I set the `pictures` field for items, but it is not working for `items-with-entity-data` which per the wiki inherits the `pictures` field from the `item` prototype:

In inventory, they show up as `item-with-entity-data`:

Inspecting the item, the pictures field is properly defined:


But it seems to be being ignored. This does work properly for literally everything else, though. I'm also pretty certain this used to work, because I remember having to write the code to specifically handle `items-with-entity-data` and once done, it worked.
I've created a minimal save with the needed mods to explore the issue.
