Ghast attack sound repeats and overlaps multiple times before firing

What I expected to happen was...:
When attacking, ghast should play a single audio que.
 
What actually happened was...:
Instead, when firing, the ghast plays multiple attack audio ques overlapping each other.
 
Steps to Reproduce:
1. Turn up your audio device nice and loud.
2. Spawn in or find a ghast.
3. Go into survival mode and allow ghast to attack you.
4. Listen to multiple attack audio ques from ghast.
 

When ghasts prepare to fire they seem to repeat the attack audio cue multiple times before actually firing.

This occurs in my realms server and on a single player survival world as shown in the video below.
