Still present as of CKEditor 4.19.0... scrollIntoView seems completely unusable with this issue. See https://plnkr.co/edit/js7F4RMPzMYi59ak as a minimal example. Try select a word then click "Scroll into view": whole paragraph is highlighted. If you simply place the cursor in the middle of any paragraph, after scrollIntoView, the cursor is moved to the start of the paragraph.

It can be worked around using something like this: const selection = editor.getSelection(); const ranges = selection.getRanges(); selection.scrollIntoView(); selection.selectRanges(ranges);

It still feels a pretty odd way to preserve ranges.
