Riding a strider will make you appear floating

Steps to Reproduce:

1. Mount a strider with a saddle

2. Ask for a friend to look over the strider's head

3. In other cases try locating a strider with a pigman on top

Observed Results:
You will see that you float above the strider and you are not really "on" the strider.

Expected Results:
You should be lower compared to the current position so it looks like you are on top of the strider.
