When setting the tick speed to anything above the default 20 TPS, any discs played in a jukebox will end prior to the audio file fully playing. Likely due to internal timer for disc being affected by tick rate. I assume this is unintentional.
Video file attached shows a demonstration of the bug and how to reproduce it.
That's because discs have a set amount of ticks before shutting down the jukebox. This is essentially the same as MC-260346.
