Wow, condescension and an exclamation point. I knew I shouldn't have commented on a grammar post by the New Yorker.

The "comma after Jr." is antiquated and pretty useless. Let it go. "Don Jr.'s" is far less visually jarring than "Don Jr.,'s" is.

Technically it is correct, but modern styling loses the period after Jr. in possessive case. Too much punctuation destroys brain synapses

I am embarrassingly fond of punctuation, and even I agree with you.

Me, too! But when you have more punctuation than letters in the target word, it's time to rethink things!

The comma in the middle of "Jr.'s" doesn't make sense.

It's due to the preceding comma, but neither seem necessary. Donald Trump Jr. Looks right to me, but they write Donald Trump, Jr.,. Dumb.
