Editor displays incorrectly in Wiki with Jetpack enabled

I've just installed the full version of the Wiki plugin and I'm getting an incompatibility where the editor is displayed three times. I tested disabling various plugins and I'm finding that the error goes away only if I disable Jetpack (current version 2.1.1). I see others having similar problems, but theirs were caused by other plugins (usually SEO). Is there a known incompatibility with the current Jetpack?

Here's my install:
