When using the spyglass with a shield on your secondary hand, the shield appears on the zoom

If you use the spyglass with a shield on your hand, the shield appaers on the zoom, wich doesn't make sense. Also, i think this happens with other items but the only one big enough to be seen is the shield

After zooming the shield souldn't appaer on the screen.

Steps to Reproduce:
1. Hold a shield
2. Use the spyglass

I've searched if someone already reported and didn't see it. I hope this helps
