As it turns out, after some initial confusion and a video review, "what happened" was Oilers superstar Leon Draisaitl accidentally tapping Smith's shot in as he was trying to support Edmonton goaltender Stuart Skinner.

Smith’s shot was fired from a sharp angle and appeared to be heading wide before Draisaitl, in an attempt to cut off the lane, inadvertently redirected it into goaltender Stuart Skinner's goal with the netminder outside of position and the puck already past him.

Leon Draisaitl had two assists in the Oilers' Game 3 loss against the Golden Knights, but his own goal stole all the headlines.
