New tumblr site broken on epiphany 3.6?

[Michael Knepher <mknepher bluethingy com>]

Tumblr has appeared to have made some changes to their site in the past week or so, and they appear to be using jquery libraries to handle a lot of the links (reblog, new posts, etc). When clicking on these in the latest version of epiphany on fedora 18, the link graphics animate to show a click has occurred, but other than that, nothing happens. Is this an issue with the version of webkit epiphany uses? Or are there possibly some jquery bugs being exposed here?
