Caused by #113504 While basic cycle aware keying works, there is a special case when inserting the first key. In that case, after the key has been inserted, it is duplicated and moved around so the FCurve range from first to last key is exactly the range of the action. It also auto-creates the Cycle modifier on the FCurve . Fix the issue by calling the function that does the key duplication and cover with unit tests.
