Resize of CKEditor in Chrome results in weird artifacts

[yuhai]

Issue: When user inputs large text in ckeditor, the scrollbar shows. Resizing ckeditor to the bottom edge of the browser results in artifacts and resize is cancelled.

Reproduced Steps: 1.Open ckeditor.com/demo#bbcode or ​http://ckeditor.com/demo#full with Chrome 2.If Chrome is maximized, return it back to normal 3.Paste enough text to make the vertical scrollbar appear 4.Click on the bottom right corner to resize ckeditor 5.Resize the ckeditor, move the mouse to the browser's bottom frame release the click there 6.ckeditor size will go back to what it was
