Due to CL-20816478 UMovieSceneSequenceTickManager now calculates DeltaTime per Group instead of using DeltaSeconds directly. As a result, the FixedTimeFramerate in the project settings is being ignored.

Licensee solved this issue by changing UMovieSceneSequenceTickManager to use DeltaSeconds directly. By the way, Setting Lock to Display Rate at Runtime and bAllowRounding to false did not solve the issue.

Steps to Reproduce
  1. Open repro project 
  2. PIE

Expect : 
OutputLog keeps showing Delta Seconds = 0.016670
Result : 
Sometimes DeltaSeconds outputs a value different from 0.016670. i.e. ignore the FixedFrameRate setting
