when we crop illustrations using the editor crop tool,
the resulted image will disappear as soon as we save the update.
we have this issue because we cannot get the right svg string using
toDataURL on the new cropped canvas with mimetype = 'image/svg+xml'
(see 'web_editor.image_processing' > 'applyModifications')
To solve this issue we set svg illustrations as uncroppable (for now).
