Drag & Drop in Firefox can destroy the editor

[Alfonso Martínez de Lizarrondo]

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

[Piotrek Koszuliński]

Firefox clones entire editable when D&Ding. Unfortunately, since we don't handle D&D and it doesn't trigger paste, we're not able to handle this in decent way now. In fact, we'll have investigate if it's possible to handle this at all.

Problem can be reproduced in v4 and Firefox only

This clearly look like regression:

1. In v3 In it is possible to drag and drop images
2. In v3 we don't have inline and divarea sample.

To reproduce try in divarea sample to select red from Little Red Riding Hood and move it to get Little Riding Hood Red. You will get whole <span id="cke_editor1 pasted

Another way:

1. In divarea sample presss CRTL+A, CRTL+C
2. Go to inline all sample
3. Click in one of editing areas and press CRTL+V

Result: you will get 12 <span id="cke_editor1

This is not a regression. v3 doesn't support divarea nor inline editing.

Perhaps this part should be reported in separate ticket

In v3 In it is possible to drag and drop images

This is not possible even in iframe based dialog so this oiece is a regression.

I've pushed a fix for this on t/9571 on both cksource and tests.

This will fix the DnD issue. As for the image selection, I'll be opening a new ticket right now.

[Frederico Caldeira Knabben]

#9584 has been opened for the image selection issue.

[Frederico Caldeira Knabben]

Fixed with 41e6adc.

For the records, there is an issue with IE8 that throws an "Unknown Error" if we use <div> for the main structure. That was the reason for having chosen <span>, in fact.
