Description

FSequencer::UpdatePlaybackRange does not check the exclusivity of the new bounds when setting them, but UMovieScene::UpgradeTimeRanges does.

Steps to Reproduce
  1. Create an actor sequence
  2. Check the option "Keep Playback Range in Section Bounds" in the playback menu on the sequencer toolbar
  3. Add a transform track
  4. Change the length of the transform track section to be bounded (not infinite)
  5. Observe via code breakpoint in `FSequencer::UpdatePlaybackRange` that the playback length of the sequence is inclusive of a round frame number
  6. Save and close the asset
  7. Reload the asset
  8. Observe via code breakpoint in `UMovieScene::UpgradeTimeRanges` that the playback length of the sequence is now exclusive and has added one tick
