Hovercards not reliable on Safari?

[annie]

I just added @Anywhere hovercards to my site, right before :

<script type="text/javascript">
	twttr.anywhere(function (T) {
		T("#twitter").hovercards();		
	});
</script>

This works reliably well for me on Chrome and Firefox, and reliably poorly on Safari 5.0. The only time I can get the @ links and hovercards to show up is to clear my cache. Any subsequent refreshes won’t show the @ links.

I’m not seeing this behavior on https://dev.twitter.com/docs/anywhere/welcome. Is there something simple I should be doing to make this work in Safari? I’m currently pulling from the Twitter RSS feed of a single user (with plans to move to the API soon). Could that be my problem?
