Attack speed stat does not correctly affect the attack speed of items

Summary

Setting the player's attack speed stat does not correctly modify the attack speed of the item they're holding.

Steps to reproduce

https://pastebin.com/7TFprK9G Making an item like such to set the player's attack speed when they're holding it.

Current behavior

Holding the item will correctly set the player's attack speed stat to 1.0 (confirmed through placeholders) but the weapon itself will have -1.4 attack speed.

Intended correct behavior

The weapon's attack speed should also be 1.0.
