Fox incorrectly holding spyglass

The bug

Something is kinda off when you get a fox to hold a spyglass.

How to reproduce

1. Summon a fox which is holding a spyglass, through using the following command:

   /summon minecraft:fox ~ ~ ~ {NoAI:1b,HandItems:[{id:"minecraft:spyglass",Count:1b}]}
   

   →  Notice how the fox holds the spyglass awkwardly
