Document mode of HTMLPane

[nk]

Hello, isomorphic,
I am using SmartClient Version: v8.3p_2013-04-04/Enterprise Deployment (built 2013-04-04) and due to some limitations of IE, I am using compatibility mode on IE11.

To display web content on my product, I tried to use HTMLPane but it's not working well. IE11 debugger showed me below.

SCRIPT438: Object doesn't support property or method 'getOwnPropertyNames'

So I opened the web site on IE11 with compatibility mode and it's running well.

Therefore, I am guessing that document mode of HTMLPane is IE8 since it doesn't support the method, 'getOwnPropertyNames'.

May I know what is document of HTMLPane?
If it's IE8, do you have any plan to upgrade it to IE9 or 10?

See FAQ: HTML5 DOCTYPE is required with IE9 and above. Do not use emulation / compatibility tags.

Without compatibility mode, the UI of my product is looks like broken.
You can refer to attached files and let me know how I can fix these without compatibility mode.
