Firefox drag-n-drop for pictures didn't work: it drops the picture, but didn't put the appropriate code in post.
Steps to reproduce:
- Click the image button
- Drag an image to the image dialog box.
- Click confirm.
- See the 'uploading' indicator appear.
Then the dialog box disappears and all we are left with is the grey overlay, no image uploaded. Clicking on the page dismisses the overlay, but no image is added.
