Drag-and-drop image bug in Chrome

[sailorzhang]

Descriptive summary - In Chrome browser, drag-and-drop image does not work if the editor does not already have content. Drag-and-drop an image from other web page causes the whole browser window to load that image.

Steps to reproduce -

1. In a Chrome browser window A, go to ​http://www.ckeditor.com/demo.
2. Click on the editor area, select all content and delete it. (Screenshot#1)
3. Open another Chrome window B, go to any page that has images, e.g. ​http://www.rolia.net (Screenshot#2)
4. Drag an image from B, drop in at the lower right area of the CKEditor in A.
5. Expected: the image is added in the CKEditor; Actual: The whole window of A loads the image. (Screenshot#3)
6. If there is already content in the editor, the operator is normal. (Screenshot#4)

Browser and OS - Current version of Chrome browser, tested in both OS X and Windows 7.

This is in fact duplicate of #10169.

What was missed here is that Drag and Drop works but only if you drop image in the first line where cursor blinks. It is easy missing that.

Source of this problem is very small content area which also results in native browser menu being shown on right click when you click below first line.

To work around this problem please refer to ​10169#comment:5
