CKeditor in modal window closes when link dialog window is open

I`ve got a problem with modal window in bootstrap. The default behavior is set to close when clicking outside of a container(it has to stay that way). CKEditor is nested in that window. Everything works great but when adding a link to a text. Ckeditor opens a new dialog window in that case and while editing that link CKeditor closes. I know the reason. Bootstrap doesn't recognize that its children and therefore recognize click on link dialog window as if outside of CKEeditor.
Is there a way to change that behavior, so link dialog window will be treated as a part of CKEditor.

this code that represents ckeditor based on bootstrap in my project. Cheers in advance!
