Bobble, no. Did it bounce within the pocket? Yes, once, but the ball never left the glove.
I should note that video replay still clearly shows the ball was secure long before Donald touched the bag.
If the ball bobbled, bounced or whatever in the pocket, which is what I saw, the player did not have control of the throw and the catch was not made until the ball was caught after the bobbled and the ball was securely in the glove. A bobble or bounce in the gooce is no control. Basic rule Definition of a catch.
