Drag and drop of image into column create duplicates

[NilakshaPerera]

I am having a problem with images being pasted twice to the column and the main canvas on the drop action of an image.

As the image below, the image element is replicated after the column

Any suggestions to suppress this ?

This is quite a hard problem to solve due to drop handle propergation.

I have a fix for it, but it is basically a hard-coded fix only for the "SimpleImage" and image block.
It would fail for other types of attachments, or if simpleImage / image was not avaliable...
