Ancient debris blocks exploding

Hi, I noticed when using a tunnel bore that if you push ancient debris at the perfect moment when a TNT explodes near it, it blows up. I thought this shouldn’t be possible since it’s blast resistant and what's strange is that it didn’t even drop the items. It might have something to do with the fact that when you push a block it has a lower blast resistance, but anyhow it doesn't seem right. If it’s not intended, I hope you get it fixed soon, because although it's a rare occurrence, it’s annoying when it happens.
