Possible bug: Invalid output for base 64 encoded SVG image data URI #314
Description
The input HTML renders the github cat logo. The output HTML fails to render the image. Re-encoding of the data URI appears to change the contents of the SVG and invalidate it. (E.g., spaces have been replaced with +.)
