Sorry for taking so long to get back to you on this.

Thanks for identifying the problem, and for the proposed fix. It certainly looks like I screwed up there pretty badly.

I won't be able to merge the PR as is, because we follow the git-flow model, which means that changes are made to the develop branch, not the master branch, and develop is merged to master only during a release. So your fix would need to be on a branch from develop (not master) and targeted to develop.

Because this is a small fix, I will make a new branch from develop with the changes so that you don't have to be bothered with rebasing your branch. Also, it is better to replace classes.find() by classes.includes() rather than the more complicated !!classes.find(c => x === name), as this was what was intended originally. I will also open an issue so that the PR has an issue that it is tied to.

Thanks again for the contribution. We appreciate it!
