Frogs don't always stand in close proximity to one another when breeding

The Bug:

Frogs don't always stand in close proximity to one another when breeding.

Steps to Reproduce:

1. Obtain some slime balls and summon two frogs around four blocks away from one another.
2. Give both of the frogs a slime ball so that they approach each other to breed.
3. Watch closely as the frogs breed.
4. Take note as to whether or not frogs always stand in close proximity to one another when breeding.

Observed Behavior:

Frogs don't always stand in close proximity to one another when breeding. In some cases, they can breed despite being two blocks away from each other.

Expected Behavior:

Frogs would always stand in close proximity to one another when breeding, like how every other entity does.
