Can't input multi-byte characters into Section macro within the page layout in IE11 and MS IME.

Muti-byte characters (ex: Japanese) are displayed as English despite transfering by MS IME in the following environment.

Environment

• Windows7 & IE11
• Microsoft Office IME 2010

How to reproduce

1. Microsoft IME set Japananese mode. IME_1.png
2. Create or edit a page in Confluence.
3. Add the page layout.
4. Add Section macro within the page layout.
5. Can't enter Japanese characters, they can't transfered and displayed in English. IME_2.png

If we use the other browsers(Chrome,Firefox..) or the other IMEs (Google), the phenomenon doesn't occur.
