Approving flagged posts / Edit posts permission

### Current Behavior

I have a group I would like to be able to review flagged posts and approve them.
I have the following permissions enabled for them
- View flagged posts
- Approve posts

This works for posts when posted on an existing discussion.
For new discussions, a flag will be raised the users in this group can view and click on.

However, this will return a [404 Not Found](https://pastebin.com/raw/yTBQbWu4) error with a spinning loading icon.

If I add the permission, "Edit posts" to the group, they are then able to view the pending new discussion and approve it.
However, I _do not want_ to allow these users the permission to edit posts, I just want them to be able to approve it.

### Steps to Reproduce

1. Enable the following permissions for the group
- View flagged posts
- Approve posts
2. User can view new discussions that need approval in the flagging system, but gets a 404 error when trying to view it
3. Add in Edit posts permission
4. User can now view a pending discussion

### Expected Behavior

I expect users to be able to view and approve new discussions with the following privileges. At a minimum, if they can't view the new thread, they shouldn't see it flagged either.
- View flagged posts
- Approve posts
