Problem can be reproduced in IE browsers from CKEditor 3.6.1 (when getSelectedText was introduced).

This method uses native selection methods and in IE something like below is executed:

console.log(CKEDITOR.instances.editor1.document.getSelection()._.cache.nativeSel.toString());

This can be simplified to:

// Get native selection and change it to string
console.log(CKEDITOR.instances.editor1.window.$.getSelection().toString());

It looks like the native toString() method for native selection returns text without line breaks.

This will require some research but from what I have checked for this test case a much better would be using focusNode.innerText which returns text with line breaks.

console.log(CKEDITOR.instances.editor1.window.$.getSelection().focusNode.innerText);
