There's an issue with your widget when used via our plugin, SiteOrigin Page Builder. I'm not stating that this issue is the fault of your plugin, only that it happens. Here's our issue on this.
When you make a change to the visual editor widget and view the history or live editor, you'll be presented with nothing (or an error if you have WP_DEBUG enabled).
Here's a reference gif of me recreating this issue:
Error:
Fatal error: Call to undefined function is_plugin_active() in D:\wamp\www\siteorigin\wp-content\plugins\black-studio-tinymce-widget\includes\class-compatibility-plugins.php on line 90
Only the relevant plugins were active at the time of testing (SiteOrigin Page Builder and Black Studio TinyMCE Widget) and Twenty Sixteen was the active theme.
