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.
