Browser becomes unresponsive at the input of the multi-byte character

[yuicom]

Page crashed when typing multi-byte characters( Japanese in my test ) after hitting enter key in any cell.

Steps to reproduce

1. Paste this HTML in source mode.

   <table align="left" border="1" cellpadding="1" cellspacing="1" style="width:100%" summary="">
   <caption>
   <p style="text-align: left;">sample</p>
   </caption>
   <tbody>
   <tr>
   <td style="height:auto; width:13%">sample</td>
   <td style="height:auto; width:85%">sample</td>
   </tr>
   <tr>
   <td style="height:auto; width:13%">sample</td>
   <td style="height:auto; width:85%">sample</td>
   </tr>
   <tr>
   <td style="height:auto; width:13%">sample</td>
   <td style="height:auto; width:85%">sample</td>
   </tr>
   </tbody>
   </table>
   
   <p>&nbsp;</p>
   

2. Change to WYSIWYG mode.

3. Try to input multi-byte characters in any cell.

Expected result

Multi-byte characters are normally input.

Actual result

Page crashed and reloaded with message said: web page is not responding.

Other details (browser, OS, CKEditor version, installed plugins)

Happened on Windows7 + IE11 and Windows8 + IE11.

Problem can be reproduced from CKEditor 4.3 in IE11 only. You change language to Japanese, input method to Hiragana and start typing. in my case page was hanging after one character typed.

Seems the culprit is <table align="left" … or <table align="right" … (center works fine).
