BUG: Zipline animation bug when holding planks or stems

[mdf25]

Description:

When the player is holding one or more grass planks/weed stems, riding a zipline with them shows the player not holding the line itself with the free hand, and moving their body as if they are running.

Steps to Reproduce the Issue:

- Construct a zipline.
- Chop down grass/dandelion/huskyweed
- Pick up one or more planks/stems
- Go to the zipline and ride it
- Player animation is broken since he is not gripping the zipline, though he can still ride it just fine.

Will add that when you choose anything from the hot bar it will do similar while on the zipline, plays the animation of switching weapons.
