Public bug reported:

The context menu exposes a saveMedia() method that allows downloading
the associated media element.

In the case of an image, when invoked there is a good chance that the
image has already been downloaded to be rendered by the WebView, so
feeding its URL to the downloadRequested signal means that the image
would be downloaded again, which is sub-optimal, especially when on a
metered connection.

For images, there should be a way to get at the raw data without re-
downloading it, if available.

For canvas elements, the downloadRequested signal could expose a data:
URI embedding the image data.

Not sure whether the same applies to video/audio.
