Interestingly, I'm able to do anything as if I'm not running. For example I can eat and drink and my player will continue running and will not perform any eating or drinking animations but it will correctly get rid of hunger or thirsty status so I'm able to run & perform actions, basically any action will work even though I'm running. I let my character run for quite some time, then disconnected and reconnected and was put in the place I had auto-ran too, so I didn't lose any progress or get teleported back. I'll try and update if I find what I do to cause this behavior.
