13870	IE11: span witch css-class turns into em-tag	AndreasT		"Hi,

i have a problem with automatic replacing of Span-tags with em-Tags.

Online test: http://jsfiddle.net/zsfwshun/

== Steps to reproduce ==

0. Only in IE11!! (IE10 not tested)
0. As you can see on JSFiddle the defined css-class is applied to my span and we see the ""italic"" formatting
1. Select the text with your mouse (not CTRL+A)
2. Start typing over the selected text
3. Click on Source-Mode button and the result is <em>Lorem Ipsum</em>

If JSFiddle is down:
1. Define your textarea as following:

<textarea id=""editor1"">
    <p><span class=""myItalic"">Lorem Ipsum</span></p>
</textarea>

2. Init CKEditor:

CKEDITOR.addCss('.myItalic {font-style: italic;}');
CKEDITOR.replace( 'editor1', {
  allowContent: true,
  extraAllowedContent : 'span(*)'
} );

== Expected result ==

<p><span class=""myItalic"">My new Lorem Ipsum</span></p>

Span tags should not be replaced with em-Tags like in other Browsers (FF, Chrome, ...)

Google Chrome (46.0.2490.80)
Mozilla Firefox (41)

== Actual result ==

The output in Source-Mode is:
<p><em>my new text</em></p>


== Other details (browser, OS, CKEditor version, installed plugins) ==
CKEditor version: 4.5.4
