after IE11 update, cursor position error in enter_br mode

[nnshg]

Hi,

We are korean developer, and we are using ckeditor for create/edit client pages online, and we use enter mode as CKEDITOR.ENTER_BR. In Nov 11 2014, MS released IE11's new security update (MS14-065, ​http://support.microsoft.com/kb/3003057), and after the update was installed, when we type some characters on the ckeditor, and press enter key, and cursor position moved the previoues line. This error is also ocuurs on the ckeditor enter key configuration demo page. (​http://ckeditor.com/demo#enter)

for example, if enter mode is CKEDITOR.ENTER_BR, 가나다라 (Enter Key) 가나다라 | (cursor)

is normal, but after IE11 update installed,

가나다라 (Enter Key)나다라 | (cursor) 가

is occured. (the cursor position is located the previous line) (In ENTER_P and ENTER_DIV the error does not raises.

and typing Korean charactor raise the error. Alphabetical and numeric charactor does not produce this bug.)

why this error couurs? and when the patch of this problem fixed will be released?

Thanks.

for example, if enter mode is CKEDITOR.ENTER_BR,

가나다라 (Enter Key)
가나다라 | (cursor)

is normal, but after IE11 update installed,

가나다라 (Enter Key)나다라 | (cursor)
가

is occured. (the cursor position is located the previous line)

I have tried to reproduce this problem but haven't managed to. From description it looks like it is enough to set Korean in IE11, change keyboard (In my case I have set default keyboard setting - Hanja Convert) and try it in enter BR sample.

@nnshg could you tell me which windows you use, and what keyboard settings you have used (screenshot is also welcome). If there is anything special in reproduction steps, please describe them in detail.
