Problem with the title size and position

Hi,
Thank you for your plugin.

When I write a new article, the markers did show up, but the size and the position of the title changes.

Screenshot with the normal positon: https://drive.google.com/file/d/0ByfHHhUHaTEqMzMybGpYTVN2Tm8/view?usp=sharing

When the article is marked as read, everything come back to normal.

Do you have any idea on how to fix this problem?

Regards

Emmanuel
