Miklós Győrfi commented on CAUSEWAY-4045:
-----------------------------------------
Sorry, I was not right. The standard base64 encoding fully supported in data
URL-s according to [https://datatracker.ietf.org/doc/html/rfc2397]
So only the svg MIME type is the issue.
> [BUG] DataUri record uses invalid SVG media type and unsafe Base64 encoding

> {panel}
> * The {{org.apache.causeway.commons.net.DataUri}} record (introduced in
> Causeway 4.0) has several compliance and interoperability issues with RFC
> 2397 and W3C standards.
> h3. Incorrect SVG MIME Type
> {{DataUri.ImageType.SVG.mediaType()}} currently returns {{{}image/svg{}}},
> while the correct IANA-registered media type is {{{}image/svg+xml{}}}.
> This causes rendering failures in browsers and in Wicket image components
> when SVGs are embedded via Data URIs.
> *Expected:*
> {{image/svg+xml}}
> ----
>
> h2. Expected Behavior
> * {{ImageType.SVG.mediaType()}} returns {{"image/svg+xml"}}
