that would tend to indicate an issue with bbpress and elementor working together, which I have already seen with their Hello theme.

bbpress works to WordPress standards, many theme builders exist because they see WordPress as a restriction and feel they can offer improvements, so stretch and alter what WordPress does, which can then can make plugins have issues.

Because it is open source, and there are no definitive rules, it is wrong to say that it is a bbpress problem, or indeed an elementor problem or a divi problem, each makes their own code to work, but you cannot guarantee interoperability of everything with everything.
