9571	Drag & Drop in Firefox can destroy the editor	Alfonso Martínez de Lizarrondo	Frederico Caldeira Knabben	"Using the divarea or massive inline samples and Firefox:

Load the sample http://nightly-v4.ckeditor.com/3753/samples/divarea.html and select some text (selecting the picture doesn't work and it's really strange but I don't know if that's a new setting), and drop it in other place for example try to select ""Red"" and change from

{{{Little Red Riding Hood}}}

to 
 
{{{Little Riding Hood Red}}}


Result: Red moves to a new line with border... 
it turns out that the whole container div has been inserted inside the editor, switching to source and back to designs makes the ""Red"" block hide, although it's still there.

Similar problems happens with the massive inline sample http://nightly-v4.ckeditor.com/3753/samples/inlineall.html.

Other browsers seems to behave correctly
