Editor scrolls to top when focused or when dialog is opened.

[Jakub Ś]

Steps to reproduce

These are two issues in fact. First one concerns opening dialog when editor is not focused and second one is the continuation of #14659.

Test Case 1

1. ​http://dev.ckeditor.com/ticket/14659#comment:6. Test case from that comment is still reproducible (starting from 4.0.0).

Test Case 2

1. Open sample page - replacebycode.html or divarea.html
2. Scroll editor a little bit without focusing it
3. Open Link dialog

This test case can be reproduced in both classic (starting from 4.4.6) and divarea editor (starting from 4.0.0)

Expected result

Editor should not scroll.

Actual result

In both cases editor will be scrolled to top.

Other details (browser, OS, CKEditor version, installed plugins)

Problem can be reproduced in Chrome browser only

Moving to 4.6.2 minor release, as 4.6.1 is mostly about polishing 4.6.0.

Here's an admittedly blunt, yet working solution.

Reasoning: we have no control over what exaclty happens when a native method is called, so we need to work around it.

Fix is working fine, but it lacks unit test. It shouldn't be too hard to create. I'm also not sure if it wouldn't be better to apply this fix only to Chrome.

Replying to t.jakut:

Yeah, I probably should.

Added unit test, changes pushed to ​branch:t/14894.

LGTM, I've just polished it a bit and merged to major with ​git:af78e85.
