This is not an out on a tag.

I forget the name of the catcher ( I believe it was Evans of the Braves a few years back), but the same thing happened. A play at the plate, the ball gets bobbled and the glove goes out instinctively followed by the hand grasping the ball. The catcher's mitt separated the ball from the player. It was a great (albeit difficult) call to make.

Sure, the player has secured possession of the ball. But just like the run down play that has a player barehand a ball and tag the runner with the empty glove, the runner is not out by tag.

I'd hate to have to make this call and luckily have never seen it happen. But, I know that it was the player who made the mistake. Those are the ones who get penalized.
