Elytra equipment sound using Leather armor equipment sound

Isn't that intended ? The Elytra are made of mostly leather and go into the armor slot.
The alternative would be "Gear equipped"

I think it's not intended. Although it is true that theh Elytra is made up of leather, it is definitely not leather "armor". It is OK to use the sound, but the subtitle must be fixed.

You wouldn't be able to tell the difference between the sounds with normal hearing (both sound like leather armor being equipped). Subtitles are supposed to stand in for normal hearing.

This issue duplicates / relates to MC-98316.
