Copper golems with a fire charge in their head slot do not display fire on their head

As of 25w33a, items in a copper golem’s head slot will display their corresponding block on their head. This works for most items which have a corresponding block, even if the IDs don’t match perfectly, but for some reason fire charges (which place fire when used, much like seeds items) do not work.

Example reproduction commands:

/summon minecraft:copper_golem ~ ~ ~ {equipment:{head:{id:"minecraft:cocoa_beans"}},NoAI:1b}
/summon minecraft:copper_golem ~ ~ ~ {equipment:{head:{id:"minecraft:wheat_seeds"}},NoAI:1b}
/summon minecraft:copper_golem ~ ~ ~ {equipment:{head:{id:"minecraft:redstone"}},NoAI:1b}
/summon minecraft:copper_golem ~ ~ ~ {equipment:{head:{id:"minecraft:sweet_berries"}},NoAI:1b}
/summon minecraft:copper_golem ~ ~ ~ {equipment:{head:{id:"minecraft:fire_charge"}},NoAI:1b}

Expected results: these would respectively display a cocoa pod, wheat crops, redstone wire, a sweet berry bush, and fire.

Actual results: they display a cocoa pod, wheat crops, redstone wire, and a sweet berry bush. However, the fire charge displays nothing at all, which is obviously inconsistent.
