7458	"Line breaks inserted when toggling between ""Decrease Indent"" and ""Increase Indent"" in lists"	Jakub Ś		"Paste the following code and switch to wysiwyg mode. 
You can always create such list your self in CKEditor.
{{{
<ol>
	<li>
		i1
		<ol>
			<li>
				i11</li>
			<li>
				i12</li>
			<li>
				i13</li>
		</ol>
	</li>
	<li>
		i2</li>
	<li>
		i3</li>
	<li>
		i4</li>
</ol>
}}}

Place the cursor behind (or before) 'i11' element. 
Now toggle between ""Decrease Indent"" and ""Increase Indent"" (in that order) few times.
You will see that line breaks (br tags) are inserted after 'i11' element every time you press a button.

This happens in FF browsers only.
It has first showed up in CKEditor version 3.5.1.
