Player can't affect redstone

Description

The player cannot trigger any of the pressure plates or tripwire. I can still bump around minecarts and entities but not triggerable things.

What I expected to happen was...:
Walking over a pressure plate/tripwire should've triggered it and opened a door.

What actually happened was...:
The pressure plate/tripwire was unaffected.

Steps to Reproduce:
1. Place pressure plate/tripwire with a redstone output

2. Observe that the redstone output isn't activated

3. Toggle perspective and observe that the player is invisible

4. Press F3+B to show hitboxes and observe even more that the player's hitbox is gone

5. Open inventory and see that the player and hitbox are visible...
