Issue has been reproducible from CKEditor 3.6.3 rev. [7374] and only in IE8 and IE9.

It looks like when you start selection below text, finish it outside of editor and press Backspace it acts like Back button.

To reproduce:

1. Copy attached file to _samples folder and open it in IE8 or IE9
2. Make a selection from right to left and make sure that you start below the sample text and let go the mouse button when you are outside of editor.
3. Press Backspace button.

Another use case:

1. Start selection below text, finish it outside of editor and press bold button or (See attached image IE.png) Start selection in white area between grey border and | ^ This is ... and finish it at the end of This^ for example.
2. Click Bold icon or apply background-color.

Result: Cursor moves back to beginning of text.

In additional to the ticket issue, the patch also addressed the following bug in IE7:

1. Start a text selection, outside of body, from left to right;
2. Move mouse back to the start point of the above selection, to it's left;

• Actual: The text selection is discontinued because of that.

[Frederico Caldeira Knabben]

The patch made the selection even harder now, as the user cannot risk crossing the editing area boundaries:

1. Start the selection af the bottom right and move to the top left a bit to start selecting.

2. While selecting, move outside the editor to the top.

3. Return to the editor to continue the selection.

It will not work (IE8 at least). The selection will be frozen at the moment we leave the editor on step 2.
