CKEditor Error when GravityForm in Modal

When I have a GravityForm form loading in a modal window, the text area fields aren’t selectable, can’t input anything. When I checked the browser error console, I found errors related to the CKEditor – here’s a screenshot of the error console: https://www.dropbox.com/s/l5e4ozpxt0mu6x8/screenshot-gf-ckeditor-error-modal.png?dl=0

The page link is an example of two forms I’m using, opening in modal windows.

Thanks,
