Dragging an inline widget outside of span, carries leftover span around

[Alfonso Martínez de Lizarrondo]

Steps to reproduce

1. Load CKEditor with the image2 widget and for easier testing

   config.allowedContent = true;
   

In the content add

<p><span style="border:2px solid red; padding: 10px">A span <img alt="" src="/userfiles/dnv.png">.</span></p>

(adjust image path as needed)

2. In design mode drag the image out of the span

Expected result

The image element is moved out cleanly

Actual result

A span wraps the image that is now out of the initial span

Other details (browser, OS, CKEditor version, installed plugins)

Tested with Firefox, Chrome and Edge

This is now confirmed to be a regression introduced in 4.5.0.
