[TECHNICAL-SUPPORT] LPS-34838 Navigation Portlet configuration - Preview breaks and portlet seems like it would be undeployed in Internet Explorer 8 (IE8)

Hy Byran,

(Here comes the rebased pull of https://github.com/blzaugg/liferay-portal/pull/32. 

GitHub handles something incorrectly, because this page cannot show my commit :(
But, if you check https://github.com/blzaugg/liferay-portal/pull/33/commits, you can see my one at the bottom of the page.

Let me know, if you've troubles on fetching my branch.)

I made a workaround-like solution for this problem: http://in.liferay.com/web/global.engineering/forums/-/message_boards/message/1348228?p_p_auth=1Nxm4uMT

I've tried to modify
"frag.innerHTML = html;" to "frag.setContent(html);" in dob-base.js#_create, but it's not supported. :S

Even if it's really a YUI bug, we need something for trunk/ee-6.1.x & of course for the customer.

So far, it works.

Could you please review my changes & forward it in case you think it's reasonable? I've added some comments to my changes.
Let me know, if you've a more simple solution.

I can send another pull to ee-6.1.x, if Brian rejected to commit this one to master: https://github.com/lipusz/liferay-portal-ee/tree/LPS-34838-ee.6.1.x

Thank you for your help.

Regards,
Tibor
