Scrolling issues in modern browsers when document is in Quirks Mode

[Rick Schnorenberg]

Steps to Reproduce

Standards mode Example: ​http://jsfiddle.net/SdL9u

Quirks mode Example: ​http://jsfiddle.net/SdL9u/1/

1. Open the sample pages linked above in Internet Explorer 11, Firefox, or Chrome
2. Click the Scroll to Paragraph X buttons above the editor to scroll to the three paragraphs with ids

Expected Result

The paragraph named in the button is scrolled into view when the button is clicked

Actual Result

In standards mode it works as expected, but when the editor's document is in Quirks mode scrolling only works in the forward direction on IE 11 and Firefox, and does not work at all in Chrome.

Browser

I can reproduce this in Internet Explorer 11, Firefox, and Chrome.

Internet Explorer 9 and 10 work correctly.

Problem can be reproduced from CKEditor 4.3 beta in all browsers except IE9-10.
