Guys, I think I know what this is. The internal identifier for this thing is "item.glow_frame"; The "Glow Frame" was first added to the MCBE in 1.16.210.59, but was temporarily removed after one patch due to a bug that caused the game to crash. It was then reintroduced in 1.16.200.52 with Goat and Snowpowder, during which time the bug started to appear (1.16.200.50) around this time. So it's reasonable to suspect that the bug is because the tester fail to p clean up the base code the first time they removed the glow item and that's it
