An infinity bow does not cause the normal effect for tipped arrows

Put the summary of the bug you're having here

What I expected to happen was...:
I enchanted my bow with infinity via anvil and enchanted book, and I expected tipped arrows to act like normal arrows that were infinite because of the bow.

What actually happened was...:
I enchanted my bow with infinity via anvil and enchanted book, and I launched a tipped arrow but the infinity did not work

Steps to Reproduce:
1. Enchant a bow with infinity
2. have at least one tipped arrow
3. fire the tipped arrow
