bug

- What is the current behavior?

If an entry is modified, saved, and published from the editor screen, the markdown widget reverts back to the old content when "Publish" is clicked. This doesn't seem to happen with any other widgets, the preview continues showing the new content, and it resolves if you go out the the collection view and back in.

- If the current behavior is a bug, please provide the steps to reproduce.

1. Edit the markdown for an existing entry.
2. Click "Save".
3. Change status to "Ready" (in the editor, not on the WorkFlow page).
4. Click "Publish" (in the editor, not on the WorkFlow page).
5. Not that the markdown editor does not show your changes, although the preview does.

- What is the expected behavior?

An entry should always show the correct content.

- Please mention your CMS, node.js, and operating system version.
