I posted this on Domain access, but to be fair, I'm not sure where the problem may reside. I'll try to investigate further, but for now, this is an FYI in case someone runs into the same issue.

Looks like related issue was marked as Closed (outdated) a few months ago, after more than two years of inactivity, which is the case for this issue as well:

Since there has not been any feedback or activity on this issue for more than two years, it is safe to assume the problem could have been resolved by more recent updates and code changes.

The problem would probably need to be tested again with more recent versions of the module and Drupal core.

Marking issue as Closed (outdated), for now.

Thanks again for your interest in the Block Class module. 😊
