iOS 7 and below in Safari - timelines won't trigger

I making banner ads and I have a video that triggers a new timeline when the video starts playing and is finished playing. It works great across everything but Safari iOS 7 and below. You can hear the video playing but the timeline animations do not work. Is this a known issue and is there a work around?

Can you share a demo document to show the issue?

Sure, here’s a link to the live ad and the files are attached.
