Videos continue to play after navigating away from the window

To add to the above, I've been testing on a different .story file which has a mix of the 3 Slide Properties (Resume, Reset, Auto) and pauses if moved away from the LMS window it's playing within.  So as a test, I changed 4 Slide Properties and uploaded into LMS and now it doesn't pause.  I've even reset the 4 Slide Properties I changed and it still doesn't pause.  My conclusion here is there is a bug... unless anyone can help.

As I understand it, you're experiencing an issue where the video continues playing in the background when you switch to or focus on another browser tab or window. Is that correct?

Hi Nedim, yes video continues when switching to another browser or window.  

I've repeated the same test a few times now on a copy of a .story file that was working, by changing 11 slides from Resume Saved State to Automatically Decide; then Saved, then uploaded to LMS - it failed and continued playing the video when I switched windows.  So then I changed the same 11 slides from Automatically Decide back to Resume Saved State, and Saved, then uploaded to LMS.  It failed again.

are the videos integrated directly into the course or do you use "video from website" ?

is the course running in lms in an iframe - do you see buttons or other decorations around the storyline course in the same browser tab?

I've been doing tonnes of testing and have success.  Basically, I have 2 laptops... one has had the recent Storyline updates applied and the other hasn't.  The one that has had the updates, is the one that is causing the problem, and the one that hasn't had the updates works perfectly fine and pauses the videos if moved away from the window.

Is there any difference in how video plays between Firefox and Google Chrome, regardless of the SL version? Or does video playback only pause in Firefox, while continuing in Chrome? I've found that this behavior is mainly managed by browsers, regardless of the SL version.

Switch to the static video publishing setting. If the problem persists after making this change, try running the JavaScript code below using an 'Execute JavaScript' trigger when the timeline starts on this slide. Does it make any difference?

let video = document.querySelector('video');
document.addEventListener("visibilitychange", () => {
  const { visibilityState } = document;
  if (visibilityState === 'visible') {
    video.play();
  } else {
    video.pause();
  }
});
