It's not made clear that editing a suggestion will bring it back to "pending approval"

I just edited a suggestion on the feedback site to correct a minor error, and now the suggestion is back to "pending approval". Now not even the pre-edit version is publicly viewable.

The edit wasn't anything important, but I still didn't think twice before doing it, because I didn't know what would happen. If I had known that it would take the suggestion offline temporarily, I wouldn't have bothered editing it.

It did occur to me that edits might need to be approved, but I figured it would just show the approved (pre-edit) version in the meantime. What would be ideal would be to do that, and display a message saying "This post has changes pending approval" or something to that effect. But if there's some reason that can't be done, there should at least be a prominent warning on the edit page (perhaps even with a check box to confirm) saying something like:

"Warning: After submitting your edit, this suggestion will be removed from public view entirely pending approval of the new version. If this is not desired, consider posting a comment instead."
