IP vs catchers obstruction

[RKBUmp]

Taken from another site. Interesting situation brought up. FED rules but believe Asa treat would have same ruling. Runner on 2 pitcher intentionally roles the ball toward home plate. Runner is stealing on the pitch but before ball gets to the plate catcher steps out in front and picks up ball.

There are 2 infractions on the same pitch with completely different outcomes. The IP would advance the runner and add a ball to batters count while the Co would be a dead ball return runner to 2nd and put batter at 1st base. Does one infraction take precedence over the other or do we try to enforce both rulings? Advance the runner to3rd on the IP and put batter on 1?
