Video inserted as Web Object does not autostart

I have a video clip wrapped with JW Player to play on a web page.

I inserted the web page as a Web Object in Storyline. 

The video autostarts on the webpage, but not in Storyline when I test the module on the web and on our LMS. 

Is this not supported in Storyline? I don't have an example to post, but if you need it, then I will create a mock-up. 

Thank you!
