Magic line does not display properly

[Artur Delura]

Browsers: All

1. Open magic line sample: ​http://presets.ckeditor.dev/4.4.0/full-all/ckeditor/samples/plugins/magicline/magicline.html
2. Set following content into editor

<p></p> <hr /> <hr />

3. Try to insert line between hr tags

Actual result: Magic line is not displayed in proper position

Please note: when add more hr tag, then magic lines are displayed between some of them.

Problem can be reproduced in every browser from CKEditor 4.0 beta.

Once you insert first hr, magic line will show up between hrs.
