[Plugin: Front-end Editor] Multisite with Domain Mapping?

I love the Front-end Editor plugin and use it extensively. However, when I tried it on a Multisite install that uses the WordPress MU Domain Mapping plugin, I couldn’t make it work. The plugin behaved like it normally should, except that the double click didn’t do anything.

Could this be due to the fact that the jquery link is to the host domain (like such: hxxp://multisite.com/blogname/wp-includes/js/jquery/jquery.js?ver=1.4.2) and not the mapped domain (like such: hxxp://blogname.com/wp-includes/js/jquery/jquery.js?ver=1.4.2)?
