CKEditor error

I get error in CKEDITOR
http://webix.com/demos/admin-app/#!/app/product_edit

Type something in editor then switch between tabs. You will see that the texts is disappeared and throws Uncaught TypeError: Cannot read property ‘getSelection’ of undefined

Yep, I can confirm the issue.
CKEditor doesn’t work correctly with in tabview. In webix 2.4 we will add an alternative mode for tabview that allows to use CKEditor and any other IFRAME based components.

OK. I will be waiting for webix 2.4.
Thank you.
