That's my expectation--the #3 conductor entombed in the plastic of the cap body isn't insulated properly. The spark shorts to another cylinder. Better caps have more or better insulation--the plastic is a higher grade, or thicker.
Someday, I'll pull the cap out of the box and see what #3 shorts to.
