Gravity forms – editor issue

After Make 1.7 I experienced the issue with editor in Gravity forms – in settings confirmation and notification editor. While in visual editor, all content is empty. It works only in text editor where everything works well. While select to visual editor, all content disappear and it’s not possible to type anything there.

The issue persist with all versions of Make after 1.7 update, on fresh installation of WordPress too.
Any idea?
