_No response_

### Description of the bug

If you, and another dragged human are both on harm intent and standing up, pulling them into your direction will push you both along. Theoretically, this could be used to speed up people with fractures, but otherwise can't noticeably increase the speed of anyone since the grab slows you down significantly.

### What's the difference with what should have happened?

Dragging things into yourself probably shouldn't push you and the dragged object along.

### How do we reproduce this bug?

1. Go on harm intent, and have another human on harm intent
2. Grab them and pull them 'through' yourself
3. Observe that you have both been pushed along and the grab is not broken
(optional) 4. Attempt to run at the same time as doing this to gain any noticeable speed increase (doubtful)
