13625	Numbered List adds items when switching from Source to Preview Mode	Alex Gorale		"CKEditor 4 with the current Editor Options configured:
{{{
                language: 'en',
                uiColor: '#741275',
                allowedContent: true,
                removePlugins: 'image',
                extraPlugins: 'image2,uploadimage,colorbutton,table,tableresize,tabletools,dialogadvtab',
                filebrowserImageUploadUrl: '/scripts/uploadImage.php',
                colorButton_enableMore: true
}}}

Replicate:
Open Page
=> Add/Remove Numbered List
=> Add some items to the list

My test source:
{{{
<ol>
	<li>item1</li>
	<li>item2</li>
	<li>item3</li>
</ol>
}}}
In Source mode add some line breaks between items

Test Source now looks like:
{{{
<ol>
	<li>item1</li>
	<li>item2</li><br>
	<li>item3</li><br>
</ol>
}}}
Toggle between Source/Preview mode. CKEditor will start adding line breaks and list items

After 1 iteration Test Source now looks like:
{{{
<ol>
	<li>item1</li>
	<li>item2</li>
	<br />
	<li>item3</li>
	<br />
	<br />
	&nbsp;
</ol>
}}}


Keep toggling and it becomes
{{{
<ol>
	<li>item1</li>
	<li>item2</li>
	<br />
	<li>item3</li>
	<br />
	<br />
	<br />
	<br />
	<br />
	<br />
	<br />
	&nbsp;
	<li>&nbsp;</li>
	<li>&nbsp;</li>
	<li>&nbsp;</li>
	<li>&nbsp;</li>
	<li>&nbsp;</li>
</ol>
}}}

== Expected result ==
CKEditor should not add line breaks and new list items. Hopefully it would just remove the line break tag.

== Actual result ==
CKEditor adds line breaks and list items
