The Zero-Width Non-Joiner shows as a "ZWNJ" box

The ZWNJ are supposed to be invisible, but currently the symbol shows up as a ZWNJ box, which defeats the purpose of a zero-width non-joiner

Reproduction Steps

1. Copy "د‌ﻦﻳء ﻮﺗﺎﺑ"
2. Paste it in the Minecraft chat

Observed result
The symbol appears as a box with "ZWNJ" in it

Expected result
It should've show up as "باتو ءين‌د"⹁ without the box
