Div Editing Area add-on stripping form tags

[Michael Muller]

Steps to reproduce

1. Have any working current installation of CKedit
2. Go to installer page and add Div Edit Area add-on
3. Test source-wysiwyg-source roundrip to see that form tags are converted to p tags

Expected result

Form tags are not stripped

Actual result

Form tags *are* stripped.

Other details (browser, OS, CKEditor version, installed plugins)

My build-config.js file is attached. If you use it as-is you will see that form tags are not stripped. Using this build, add Div Editing Area, and try again.

Thanks for your help!

Working build that does not strip out form tags. Note that the Form Elements add-on is not included, yet form tags are still not stripped.
