The Bug:
You can extinguish candles and candle cakes in adventure mode by using wind charges.
Since MC-204707 was fixed, candles cannot be extinguished by hand in adventure mode, and since MC-270849 was fixed, wind charges from breezes cannot extinguish them while the mob_griefing game rule is set to false. However, wind charges thrown in adventure mode still extinguish candles and candle cakes, therefore introducing an inconsistency.
Steps to Reproduce:
Place down a candle and a candle cake, and light them both.
Obtain some wind charges, switch to adventure mode, and throw a wind charge at each of the said blocks.
Observe if the said blocks were extinguished.
Observed Behavior:
You can extinguish candles and candle cakes in adventure mode.
Expected Behavior:
You would not be able to extinguish candles and candle cakes in adventure mode.
