Hi Daniel,
copying images to the clipboard is an important use case. Do you have any
suggestions for how we could meet this use case in a safer way? For
example, would it be safe and easy to add a little bit of "magic" to make

clipboardData.items.add(canvasElement)

put a PNG on the clipboard? Perhaps copying a rendered imgElement should
work too?
