Looks like you still need to add the Confirm .js and .css files to the head and you still have to change the error message class references after the confirm field.
You have updated the script .js code properly.
It will likely be a week or two before we are able to get out the update. I may be able to get a beta out to you personally quicker but we have to go through a build and QA process before an official release can be available and we just discovered this issue yesterday so we don't even have it fixed internally yet.
