Happy Ghast in Minecart causes excessive lag

When a happy ghast in a minecart collides with a regular ghast in a minecart, it causes enough lag to entirely freeze the game until it is forcibly stopped. To recreate this, make a 6-block segment of normal rails with solid blocks on both ends and one powered rail on one end. On the end without the powered rail, place a ghast in a minecart. On the end with the powered rail, place a happy ghast in a minecart. When the powered rail is activated and the happy ghast moves into the regular ghast, the game comes to a screeching halt. This may relate to the happy ghast’s unique collision. I was not able to get this to happen again upon reloading the world, but it caused my player data to not be saved.
