Villagers don't show names while trading

Dear Mojang Developers, I found an interesting bug that affects the Villagers. In Minecraft Java, when you trade with a villager, it shows their name. When you trade with them, it says Level [1-5] - [Profession of Villager] and does not show their name if nametagged like unlike Java, it shows their name. 

 

If you look at the picture, you will see a villager nametagged in my survival world, and they do not show their names.

 
Steps to reproduce the bug.

1. Give the villager a name using a nametag
2. Open the trade screen, and you will only see their level and profession not their name.
