Anvil/Nametag Snapshot Bug

Overview:
When trying to rename a nametag when clicking on text box, doesn't show selection mark and when commanded /xp (very high xp point) points because i think it was the lack of xp, then i realized it was a bug when it still don't works

How to recreate:
1. Operate Minecraft: Java Edition _{Using beta version}
2. Optimized 20w09a world to 20w10a world version
3. Playing world then grabbed anvil from creative search tab
4. Grabbed nametag from creative search tab
5. Try to rename nametag then failed
6. Using command /xp (forgot how much) points
7. Trying to rename the nametag again then failed

IMPORTANT
Im using language setting to Bahasa Indonesia, maybe there is a bug within the .lang files?
