Editing idea suggestion sometimes cancels opt-in

In my idea suggestion polls, editing a suggestion sometimes results in a change to the opt-in and a message is sent to everyone that the suggestor's agreement to the opt-in has changed from "yes" to "no". Is there a way to prevent this (both the change and the message)? I think this may only happen sometimes because when I tried it, I had to check the opt-in message box in order to continue. Somehow this isn't always happening.

I tried several things:

• create idea without account, confirm opt in, edit -> no change
• create idea with account, confirm opt in, edit -> no change
• create idea with account, confirm opt in, admin edits idea -> no change

Do you know how to reproduce this?

I followed up with one of the users that had made an edit that produced this result. She confirmed that she does have to opt-in again before her edit is submitted. So, from the user side of things, it does seem to be working. This is what I see in the updates:

First message: Content was changed from * to *, Terms accepted was changed from >false< to >true<
Second message: Content was changed from * to *, Terms accepted was changed from >true< to >false<

I thought that maybe the opt-in has to be canceled in order to make the change and then they opt back in. However, the order is wrong. In any case, I think it may be the case that only moderators are seeing these messages about opt-in/out, so perhaps I will not worry.

Ok, Thank you for the details!
We are trying to reproduce this and fix it.
