Hello the great LeetCode team!

It sometimes happens that you get a successful submission (especially for new problems) then a smart guy contributes a great test case and your submission still shows "accepted" and the problem "solved", while if you resubmit you'll get "wrong answer".
The question is: can you re-run exisiting submissions against newly contributed test cases and mark a problem as "attempted" if its solution fails? Or maybe easier, can you notify the user of a newly-contributed test case for a problem they solved?

I hope I explained my suggestion well. Thank you for your great work!
