Bug - Playback speed not respected in actual demo

In edit mode, you allow us to change the playback speed of a video clip (0.5x, 2x, etc), and then click save to commit this change. Once finished, we can see that the video has slowed down/sped-up accordingly WHILE IN EDIT MODE. However, after clicking Preview or publishing the demo itself these changes to playback speed seem to be completely ignored in the actual published demo (which is where it actually matters).
