Wordpress-ios: "e>e>" strings appears in the editor after Updating the post

[hypest]

Expected behavior

Updating a post should keep the post content in the editor untouched.

Actual behavior

There's a e>e> string added to the post in the editor each time the post is pushed/Updated to the server.

Steps to reproduce the behavior

1. Open the post that gets created automatically after creating a new site on wordpress.com
2. Notice that the "Update" button is enabled/available to tap
3. Hit the "Update" button
4. After the update finishes, notice that a e>e> string is inserted in the editor

Example (HTML) content that seems to trigger the issue:

This one is pretty bad, we should at least target the frozen bunch if not hot fix when we sort it out.

This one is good to close, right?
