If you have a spirit level you can check the frame to see how far out it is and in which direction.
If the door is closing by itself then the foot of the door (as we see it) is out of plumb toward us.
Could be both though. Looks like it's wider at the bottom of the frame.
Yes, that would do it too. Although to me the stiles look a consistent width. If the carpenter hasn’t put the new frame in plumb in that plane he’s a twat.
