Cursor position on FF4+ different from FF 3.6 & other browsers

[satya]

Steps to reproduce

1. Open API Sample.

2. Place cursor at end of content in CK Editor.

3. Press "Set Editor Contents" button.

4. Press Shift+Tab twice & move focus back to content area in CK Editor.

Issue: On FF 7 cursor shows up at the end of content area.

On all other browsers (FF 3.6, IE(6,7,8,9), Opera & Safari) cursor shows at the beginning of content area.

TC from that ticket:

CKEDITOR.appendTo('demoInside', { height: 300 });

jQuery("<div />").text("CLICK ME TO FOCUS").click(function(){
    var editor = CKEDITOR.instances.editor2;
    editor.setData("line1<br/>line2");
    editor.focus();
}).appendTo("#demoInside");
