Yesterday I put two candles in the corner block of my room and lit them.  Today, I noticed that my cats would treat the candle assemblage as an "occupied block" (similar to a bed or crafting table) and jump on to or sit on them.  Doing this does not cause them injury or set them on fire (see attached screenshots).

They didn't jump on campfires or other exposed flames (such as a torch standing straight up) in the house when I tested later on..

This looks ridiculous and is counterintuitive.
