Conflicts with D&D Featured Image plugin

I’ve had issues getting this plugin to work, so I started troubleshooting and finally figuring out the source of the issue which turned out to be the Drag & Drop Featured Image plugin.

Basically, when both plugins are activated the Image Widget plugin won’t let me add an image after selecting it and pressing the “Insert into widget” button, rather, it would just force a refresh of the page I’m in (the Widgets page) making me lose my work.

You can easily reproduce this issue, just download and activate both of the plugins.
