Parrots don't stop dancing even if the music ends.

1. Summon/spawn/find a parrot
2. Tame the parrot with seeds and make the parrot sit
3. Get and place a jukebox
4. Get any music disc of your choice and right-click/tap the jukebox to 
play the disc 
5. Wait for the music to end
6. The parrot doesn't stop dancing even after the music stops playing
(Do not disturb/kill the parrot while the music is playing or after the music
stops playing because doing so will make the parrot stop dancing)

The parrot must stop dancing after the music ends.

Here, in this attachment, the music (PigSteps) ends at 0:25 but the parrot still
dances till the disc was removed.
