Toggle sprint will occasionally stops working for no reason.
While I have experienced this bug, I cannot reliably replicate the issue, making debugging extremely difficult.

The bug occurs when players switch to another item while using it.
Using an item refers to eating, bow drawing, drinking potions, shielding, or anything that requires holding right click

It seems Forge doesn't have an event where the player switches to another item while using it. Essentially stopping without triggering any of the Forge events, causing the feature to fail.
