[IE] A Japanese key input is repeated (when enter mode is set to BR)

[Wiktor Walc]

1. Set to [CKEDITOR.ENTER_BR] as [enterMode] of config.
2. This CKEDITOR is opened by IE8.
3. Input some texts in WYSIWYG area.
4. Select all contents (e.g. Ctrl+A)
5. A Japanese input is turned ON.
6. Input some Japanese text (type at least two letters).

Result: The first pressed key is repeated twice. For example, in the case of the Japanese character inputted using the [H] key and the [E] key, it will be in the state where [hhe] was inputted.

Confirmed in IE8/win7.

I haven't been able to reproduce this problem in IE8 but in IE11. In Ie8 resulat was へ while in IE11 ｈえ.

In my case when start editor with Enter Mode set to BR, select all text and type he I get "ｈえ".
