Get duration of content on the timeline to make sure the playhead moves until the end of the timeline content when the content is less than 10 seconds.
Originally it would go all the way to the 10 seconds when timeline content was less than that.
I checked how clipchamp does it and they have a min 10 sec timeline but video timeline plays at length of content, so we are doing it like the pros. timeline is jumpy though will probably work on that.
