Codesnippet checkDirty is true after modify code and then rollback or switch to source and back

[Artur Delura]

1. Open code snippet sample with following code i.e. you must modify sample source.

   <pre>
   <code class="language-javascript">a;
   </code></pre>
   
   
   <pre>
   <code class="language-sql">a;
   </code></pre>
   

2. Double click on first codesnippet widget, to open dialog.
3. Remove ; and apply.
4. Open codesnippet dialog again and rollback changes. Add ; sign where it was.
5. Apply changes.

Actual result: Calling method CKEDITOR.instances.editor1.ckeckDirty(); return false

Please note: This happend only when there are two codesnippet widgets.

@a.delura i have modified your description as I think you have meant checkDirty.

When you start editor with text like "pp", delete p (checkDirty==true) and then type p again you get checkdirty==false. One would expect same behaviour from a widget holding text-like data.

Weird case scenario with above code is that switching to source mode and back causes checkDirty to return true - it is possible that code is invalid and editor modifies it thus you get such result.
