I appreciate this feedback, @papertower, and agree with you that our configurations of Select2 should not affect instances of Select2 outside of our own plugins.
I have filed a bug report about this and will post again in this thread when there is news about an update that fixes this problem.
That could several weeks or more, to be honest—but I assure that this thread will eventually be updated with news if there is news to share.
Thanks for sharing these thoughts! Please let me know if there are any other issues or questions I can try to help with in the meantime.
Sincerely,
George
