Horizonal line is duplicated after undo (Chrome)

[ndeuma]

Create two paragraphs with a horizontal line in between, like this:

<p>a</p> <hr /> <p>b</p>

Position the cursor before the "b"

Press "Backspace" twice

Press "Undo" twice

Expected:

<p>a</p> <hr /> <p>b</p>

Actual:

<p>a</p> <hr /> <p>b</p> <hr /> <p>b</p>

Tested with Chrome 34.0.1847.131 m

I can't reproduce it on Version 34.0.1847.132 on master and on 4.4.0. Since you set version to 4.0.1 I guess you're using it what means that you should update CKEditor. On the other hand I cannot reproduce the issue on 4.0.1 too.

So:

• Please check latest CKEditor version.
• Please record a screencast if you can reproduce this TC on latest CKEditor version.
