Elements path selection and deletion work unexpectedly

[Lyuba]

Steps to reproduce

1. Start with the following source:

<div style="background:red;">some red text</div>
<div style="background:yellow;">some yellow text</div>
<div style="background:blue;">some blue text</div>

2. In WYSIWYG, place cursor on the yellow text
3. On the elements path bar at the bottom, click "div" to highlight the yellow div
4. Press delete

Expected result

I would expect the yellow div to be removed, and the result to be:

<div style="background:red;">some red text</div>
<div style="background:blue;">some blue text</div>

Actual result

Instead, the context on yellow is removed, and the content of the following blue div is replaced inside instead (along with some line-height added for some reason):

<div style="background:red;">some red text</div>
<div style="background:yellow;"><span style="background-color:blue; line-height:1.6">some blue text</span></div>

Other details (browser, OS, CKEditor version, installed plugins)

Using Chrome on Linux.

Reproducible on ​http://ckeditor.com/demo#full

I feel like this was working differently (and used to just remove the div) in previous releases.
