Problem with JetPack Edit CSS - pulls entire Post content into editor

[jekkilekki]

See the issue I initially reported to JetPack.

The Problem

It seems that with Babble AND JetPack activated at the same time, somehow Babble gets confused and pulls the entire Post content (from a Post I've assigned a custom class to an image in) into JetPack's custom CSS editor. When I edit the CSS (delete the Post content and add my custom CSS), it actually deletes the entire Post and saves my custom CSS in its place.
