Cannot target itemframes via targetters

Summary

Describe the bug encountered in detail.

Steps to reproduce

slap mob in appropriate file, slap skills in appropriate file, interact with zombie near an item frame. https://pastebin.com/8nQHrkwG

I tested with armor_stands+zombies to verify that the entity targetting worked otherwise. I tested with crying_obsidian+dirt to verify that the block targetting worked otherwise.

Current behavior

both - entitytype{t=item_frame} and - blocktype item_frame true seem to be failing to target item frames

Intended correct behavior

item_frames should identify as an entity and be targettable via @EntitiesInRadius
