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)
