It's currently not possible to edit posts where a suggested edit is pending; even if I've already placed an accept/reject vote, I just get a popup box when I click on 'edit' to approve or reject the edit. Normally this wouldn't be much of a problem, as the suggested edit could be approved or rejected - however, when the suggested edits system is turned off (as it is now) this results in posts being completely un-editable - e.g. Within resources in JAR
The suggested edits system should auto-reject all pending edits when it is disabled.
