Using shield, bow, or food while running causes speed issue

Keep running > Using shield, bow or food > Jump: speed of character while not landing on the ground is oddly fast; it seems same with the speed when running without using any item.

What I expected to happen was...:
I think it should be the same speed while using item, whether running is on or not.

What actually happened was...:
While running, if I use the item that takes times, speed while not landing is faster than walking speed.

Steps to Reproduce:
1. Keep run.
2. Use item that takes times(shield, bow, food, etc.) while running.
3. Jump, while running and using item.
