      Description

      QTimeLine uses coarse timer internally, and since it can fire prematurely, sometimes it takes QTimeLine one extra interval to finish. Please refer to the attached example.

      Note that this behavior is not present on Windows. It is present on Mac (and potentially other unix systems).

      Expected result: timeline finishes after (duration) ms.

      Actual result: timeline may finish after (duration + interval) ms.
