Inline mode + Widgets( codeSnippet or formula ): CheckDirty() always returns "true" after page is loaded

[Airocat]

checkDirty() function does not work properly with CodeSnippet and Mathematical plugins in Inline mode.

If there is a codesnippet or a formula in the ckeditor element, CheckDirty() always returns "true" after page has been loaded.

Steps to reproduce:

1. Select any editable element on the page and add codeSnippet or a Formula
2. Save the element and reload the page
3. Execute in JS console:

CKEDITOR.instances.editor_instance.checkDirty()

where editor_instance is id of the element. It will return "True" but it should be "False"

This issue emerges only in Inline mode, not in classic mode.

Software versions:

Ckeditor: 4.4.7 (custom build)

OS: Ubuntu 12.04 x86_64

Browsers: Chrome 40 and Firefox 35 (latest versions at this time)

Edit: Please also see comment:8 because this issue also occurs when you just load the editor (checked in CKEditor 4.5.6 at the time of writing).

I can confirm that this is happening in default samples. To reproduce, I have modified inline editor part accordingly.

var e2 = CKEDITOR.inline( 'editable', CKEDITOR.tools.extend( {}, config, {
	extraPlugins: 'codesnippet'
}, true ) );

console.log( e2.checkDirty() );
e2.on( 'instanceReady', function(){
	console.log( e2.checkDirty() );
	setTimeout( function(){ console.log( e2.checkDirty() ); }, 1000);				
});

I was only able to reproduce this problem in mathjax and codesnippet samples.

In case of codesnippet, the highlighting markup is not applied in CKEDITOR.instances.editable._.previousValue (only in inline).

So getSnapshot returns HTML with following widget innerHTML:

<span class="hljs-keyword">for</span> ( <span class="hljs-keyword">var</span> i <span class="hljs-keyword">in</span> object ) { (...)

While previousValue has plain text:

for ( var i in object ) { (...)

From what I have checked, this issue can be reproduced from CKEditor 4.3 beta.

I just ran across this. It seems to be the case(for formula at least) that it doesn't matter if it's inline or not. It's reproducible from the mathjax demo page(​http://sdk.ckeditor.com/samples/mathjax.html). Just load that page, open a console and CKEDITOR.instances.editor1.checkDirty() returns true instead of false.

@joncostello - from what I have checked MathJax returns true for both editors while Code Snippet returns true only for inline editor. It is enough to load editors in that case and execute checkDirty() method.
