Unlit campfires still hurt players that stand on them

Summary is self-explanatory. While originally thought to be caused by it not having a tag to determine whether it was lit or not, but it in fact does have a lit tag, suggesting it is caused by something else.

How to reproduce:

1. Place a campfire.
2. Put it out with a water bucket.
3. Stand on the unlit campfire.
   → You get damage but the campfire is unlit
