Enabling Form Fields in WYSIWYG Area

Hi All,

I'm trying to override the default functionality of CKEditor disabling form fields.

When form fields are inserted, e.g. checkbox, I would like to preserve the browser functionality. i.e. If I click the checkbox in the WYSIWYG area it will (un)check the checkbox accordingly.

I feel I am pretty familiar with CKEditor and I have developed a couple of plugins and some moderate customization, but I can't figure this one out. The obvious lies in the wysiwygarea/plugin.js line 404:

if ( ev.data.getTarget().is( 'input', 'select' ) )
   ev.data.preventDefault();

However, removing the preceding snippet doesn't work.

Your ideas/suggestions are greatly appreciated.

Thanks.
