Awaiting Feedback Prefixes User Groups Don't Have Access to Are Removed When Editing Thread Titles

If a user group edits a thread title that contains a prefix they don't have access to, it is removed after submitting the changes. However, this was recently fixed in XenForo 1.4.7, which KH-Vids is on now, making it so even if the user group doesn't have access to that prefix, it will remain usable. See my bug report here.

The fix definitely took effect as I tested it on XenForo itself and KH-Flare and the prefix I/our test user didn't have access to remained in place after saving the changes. See the fourth post of my thread here.

As I know KH-Vids has the Multiple Prefixes add-on, I'm thinking that may be where the issue is coming from.

Edit: I completely forgot to upload screenshots.
