 I moved my text widget to a different widget area, and now the content in
 the visual tab is empty, and I can’t click into the text area. If I switch
 to text, I see the content. Throughout this, I can also still see my
 content in the preview pane.

 If I save, my content remains. Then, if I close and reopen the Customizer,
 it shows back up. There are no related console errors.

 This only appears when I move the Text widget from one widget area to
 another. If I move it around within the same widget area, it's fine.

 @westonruter says:
 > The problem is when the control gets moved in the DOM the editor iframe
 needs to be re-initialized. I think we are accounting for a widget being
 reordered in a sidebar but not when moved between sidebars.
