Here’s the thing: it should.
The entire reason that Rowling revealed that Dumbledore was gay was that she was telling his backstory, and a huge part of that was his close and intense relationship with Grindelwald. Their friendship, romance, and betrayal is a story she’s had as part of his history, and this is the film that would theoretically tell that story. Avoiding that makes zero sense for people who’re fans of these characters.
