Code Sample
I can confirm the issue. However, it seems to be caused by the fact that resize handlers' positions are not refreshed after scroll:

After scrolling the handler for the first cell was still in its original position and I was able to resize that cell even if it wasn't in the viewport anymore.
@Comandeer thanks for acknowledging. Will there be any fix for this issue in the future? Or is there any workaround then please do let me know.
Thanks
~~After some more research I discovered that it's not strictly connected with the scrolling but more with the fact that the table is inside an element with the position: relative style. It seems to somehow alter the results of calculations of pillars positions (probably in the CKEDITOR.dom.element#getDocumentPosition() method).~~
The position: relative is not needed after all, however, the issue is present only in inline editors, I can't reproduce it in an iframe-based one.
