It hasn't happened yet,
AFAIK. The rule's only been in force for a year and a bit.
I assure you it will eventually, and when it does all hell will break loose, and quite rightly.
The simple fact of the matter is, now we know what we know there's no way to be fair without completely radical changes to the way cricket is played.
IE, put a brace on the bowler's arm to make sure there is no possibility of anyone's arm straightening, deliberately or involuntarily.
Yes, it's something no-one's ever remotely considered, but anything else is completely and totally unfair.
