[0.16.0.0] Floating umbrella issues?

Summary of bug here.
Only takes effect on potions that decrease size…? Switching off of the floating umbrella (or even adding it to the hotbar) makes the character have super low jump height and increased fall speed.

Steps to Reproduce

  1. Equip tiny potion/small potion

2A. Switch to umbrella then off umbrella to another item (or no item)
2B. Add umbrella to hot bar

What I expected to happen

Enjoy the awesome umbrella then switch to another item as needed while being returned to normal gravity.

What happened

Switching off the umbrella dramatically lowers jump height and increases fall speed immensely


Notes / Media

I tried really really hard to get a video of this but my computer is fighting me at every turn, it’s not hard to replicate I’m sure you could do it.
