On more update: The triggers to resume the timeline also need to check if any of the markers are open before resuming. Otherwise, the timeline audio resumes even if the the next marker is opened by clicking directly. See new attachment.

Last issue you will need to consider (at least for the way this demo is assembled) is that if you switch between browser tabs, everything pauses on the slide. When you come back, the playing of the timeline and marker videos may be disrupted. You would either need to better control how the videos are triggered in your final product, or perhaps use an eventListener to monitor for when the tab loses and/or regains focus, and play or pause the marker videos as appropriate based on the 'markerOpen_#' variables.
Perhaps see https://stackoverflow.com/questions/10338704/javascript-to-detect-if-user-changes-tab for ideas.
