Memory leak happening in CKEditor when navigating to different view

[Kunal Garg]

Steps to reproduce

1. Use CKEditor.replace on textArea
2. Now navigate to different view. This destroy the editor.
3. Recreate the editor with CKEditor.replace

Expected result

The objects allocated in the first iteration should be fred

Actual result

The objects are still there and keep on piling on repeating step 2 and 3

Other details (browser, OS, CKEditor version, installed plugins)

Showing memory objects bound to the FormElement

I debugged the issue and it is happening because of following code: form.$.submit = CKEDITOR.tools.override( form.$.submit, function( originalSubmit ) {

return function() {

onSubmit();

For IE, the DOM submit function is not a function, so we need third check. if ( originalSubmit.apply )

originalSubmit.apply( this );

else

originalSubmit();

};

});

It works fine after I set the form.$.submit = null; in destroy.

I'm having trouble reproducing this one. Could you provide a heap snapshot that demonstrates this issue?
