Interactive Video

I just discovered that the current implementation of the "submit screen" defeats the purpose (for us, anyway) of the "Prevent skipping forward in a video" feature. Essentially, users can now access the submit screen at any time, even if they have not watched the entire video or reached the point in the timeline where the submit screen was inserted. I'm marking this as a bug rather than a feature request because this new feature has essentially broken a previously working feature (that my organization partially funded).

I recently upgraded the interactive videos on my site to the latest version, and have discovered that the custom xAPI code I was using to check if the user answered all of the questions correctly or not has stopped working. I turned on showing the xAPI event statement in the console, but I do not see why my code would not still work. Here is a snippet of the code I'm using:

Hi!

In the interactive video is an option "Start video at". 
I'm wondering if there is an option "Stop video at"? It would be very usefull since it would be possible to show a short clip.
