Custom music disc music using resource packs doesn't fade out after leaving the jukebox radius while it is playing.

The resource pack has been tested in 1.13.2 where the fade-out worked, confirming that it is a 1.14.0+ bug.

The sound files have been compressed to a ogg file with a bitrate of 64 kb/s and the pack is not bigger than 50MB (related for servers)
