I got this error messages when trying to view a h5p activatie with a svg image in the content. And this dit work in the past.

This broke our existing content.

It seems that h5p documentation claims that svg should be supported.

I looked into the code and noticed this change in h5p/h5plib/v127/joubel/core/h5p.classes.php

Before:

public static $defaultContentWhitelist = 'json png jpg jpeg gif bmp tif tiff svg eot ttf woff woff2 otf webm mp4 ogg mp3 m4a wav txt pdf rtf doc docx xls xlsx ppt pptx odt ods odp xml csv diff patch swf md textile vtt webvtt gltf glb';

public static $defaultLibraryWhitelistExtras = 'js css'; 

After

public static $defaultContentWhitelist = 'json png jpg jpeg gif bmp tif tiff eot ttf woff woff2 otf webm mp4 ogg mp3 m4a wav txt pdf rtf doc docx xls xlsx ppt pptx odt ods odp csv diff patch swf md textile vtt webvtt gltf glb';

public static $defaultLibraryWhitelistExtras = 'js css svg xml';

If i add svg back to $defaultContentWhitelist, It works again for me.

Is there a reason svg was removed from this?
I hope this can be reverted so that svg in h5p content will work again.
