Prevents saves from Siteorigin PageBuilder

When the plugin is active any change to widget content (such as just text in the editor) with SiteOrigin’s PageBuilder is not saved. After de-activating the plugin things work fine. I’m using the version 1.1.3 of the plugin.

Changes to the widget content are lost also when toggling between the PageBuilder and the basic Visual/Html editor, so the problem is probably in Javascript
