Zombified Piglins aggravate when not provoked

As seen in the video, the zombified piglins are peaceful with the player. Then the skeleton shoots an arrow at the player but accidentally hits a piglin. This causes nearby piglins to attack the skeleton. Then they attack the player even though they were not hit by the player. (this is not an issue with regular piglins) 

PS sorry for the bad video quality. The video has to be compressed to fit in the 10MB limit.
