Integrate imagerotate plugin, problem with safe_html removing data:base64 elements

[gbastien]

Hi @gotcha

I am working on integrating https://ckeditor.com/cke4/addon/imagerotate

There is an issue with safe_html because imagerotate will store image as data:base64 and it is stripped...

I wonder, here in safe_html : https://github.com/plone/Products.PortalTransforms/blob/master/Products/PortalTransforms/transforms/safe_html.py#L40

Would it make sense to only remove data:text elements instead data: so data:image elements would be kept?

See you,

Gauthier
