Current Behavior / Expected Behavior

When using the default WYSIWYG editor, any time an image is dragged and dropped into the window it inserts the image twice. This only happens in FF, not in Chrome. I believe this has existed across different 2SXC versions, but we're using the latest.

Instructions to Reproduce the Problem

Create a data field of WYSIWYG and drag an image in and notice how it appears twice.

Your environment
