Timeline not show up sometime without any error

[Google Code Exporter]

Hi,
This timeline is awesome!
I'm running timeline2.3.0 locally. It works good on my site. But problem is 
when I refresh the timeline page, some time the timeline not showing up, or 
just showing a background. When I keep refresh the page, it will show up again.

The firebug not report any thing wrong.

Thank you.
