Steps to reproduce: Create a line of 9 jukeboxes and put music discs in all of them. Then, take out music discs from 8 jukeboxes.
Expected result: The 9th jukebox will continue to play music.
Actual Result: The 9th jukebox shows music particles, but plays nothing.
Environment
This bug may sometimes not happen, but almost all of the time it happens. If you do the same thing with 9+ jukeboxes, after you remove the 8th music disc, all the other jukeboxes are affected by the bug. 1st happened after I killed a chicken jockey and got the Lava Chicken music disc. I created a line of jukeboxes, and put the disc in all of them (in creative). I removed 8 discs, and found that the other jukeboxes didn't play anything, even though I didn't take the discs outta them.
tested on 1.21.11, what i believe is happening is that there is a limit on how many discs can be played at once. When using 9 jukeboxes, the last one never started playing, which when removing all other discs gave the illusion that it stopped working.
