The URL in the bug description renders incorrectly after r70546 - when typing in the entry field, the javascript-positioned autocomplete shows up in the wrong place. See http://crbug.com/62451 for more details. The popup positioning logic appears to be in http://www.d.co.il/Hebrew/scripts/acXml.js.

It's hilarious (in a sad clown kind of way) that this patch doesn't change any layout test results. We need some regression tests for this.
