Firework loses flight duration description when put in an enchantment table

Accidentally inserted a firework (tested both manually and by shift clicking, both works) into an enchantment table and it lost its flight duration text. Firework will still launch the player with the same effect when using the elytra.

Steps to Reproduce:

1: Insert firework into enchantment table (make sure it has a flight duration description)

2: Watch the firework lose its description

EDIT: Does not always happen but is very likely to happen
