I wasn't able to reproduce it with Safari 8. However, Philip could reproduce it once with the same configuration as used by the tester. But after he tried in Chrome, the issue were gone in Safari as well.

To me that sounds like a strange bug in Flash, that is triggered by the way we rewrite flashvars and reload the video, and somehow disappears when other apps (like Google Chrome) start Flash as well.

I'm closing all issues related to the legacy Safari extension, as it has been discontinued in favor of an App Extension that doesn't share any code with the old extension.
