Jukebox with disk activates TNT

While I was playing Minecraft for the third time on 1.18, I was messing around with TNT, when I took a break from blowing up a mountain experimenting. I wanted to check the new disk, other side. While I was listening, I randomly put TNT directly next to the Jukebox and discovered it became lit. After further experimentation, I discovered that it affects all disks and only activates when a disk is in.
