ClipboardInputTransformationEvent

Fired with the content, dataTransfer, method, and targetRanges properties:

• The content which comes from the clipboard (it was pasted or dropped) should be processed in order to be inserted into the editor.
• The dataTransfer object is available in case the transformation functions need access to the raw clipboard data.
• The method indicates the original DOM event (for example 'drop' or 'paste').
• The targetRanges property is an array of view ranges (it is available only for 'drop').

It is a part of the clipboard input pipeline.

Note: You should not stop this event if you want to change the input data. You should modify the content property instead.
