While it wasn’t intentionally done, this practice is now pretty commonplace in cinema – especially in superhero blockbusters. It’s not always the case that exact tracks are used from movie to movie, but films frequently reuse themes that were created for previous titles in a franchise, even in cases when there are different composers doing the work. In the case of Wonder Woman 1984, the production happened to be working with the same person who co-created the music for the feature that first introduced the titular character into the canon.
