Still tragic.
I'm disappointed this is a won't fix. It feels as though this decision severely limits the potential of the relatively new feature that is being able to load jukeboxes via hopper. The player can hear a jukebox when they walk out of range and then back in; I would like to see the reasoning behind this decision.
this seems like intended functionality, like dying a colored shulker box a different color. If you want to change your trim you can but you cant have two.

was labeled won't fix
for reasons why, we wait
