Is your feature request related to a problem? Please describe.
people don't realize they can use any candle in the minecraft:candles block tag. Same goes for custom pentacles using block tags for certain blocks.

Describe the solution you'd like
would be cool if both the in world render and in-book preview cycled through blocks in the tag being used... So for candles they would cycle through every block in minecraft:candles

@theboo I just checked and the tag renderer already does it!
However occultism explicitly sets a display tag in its pentacles, something that was grandfathered in from generating them for patchouli. Will close this here and adjust on occultism!
