With Joel being busy or lazy, I’m claiming credit for that one even though I have nothing to do with it.
Problem: Classic UI [allegedly – t.j.] has an issue in v8.x where Chrome will just keep ‘spinning’ on some of the forms without returning anything.
Solution: Add an empty JS file to the form.
Joel trying to be funny: Legacy form rendering also works if you’re feeling destructive.
Time to upgrade: Unified interface doesn’t have this issue
