Just thinking out loud: An alternative could be to use createBlock here. That way we wouldn't need to add any extra public functions to @wordpress/blocks.
const sanitizedAttributes = createBlock( block, attributes ).attributes;But I suppose it makes sense for @wordpress/blocks to have sanitizeBlockAttributes as it might be useful in other situations? What do you think?

Clever! But I fear that it's semantically incorrect? In the future, we could add more logics to the createBlock factory than sanitizeBlockAttributes only, that would be hard to catch any unexpected side-effects here.

Description
Originally raised in #29111 (comment).
The problem is that the endpoint
<ServerSideRender>is using will try to validate theattributes. Since we're passing__internalWidgetIdnow (#29111) to every blocks in the widgets screen, this breaks on the server side.The solution is to sanitize the attributes before sending them to the server. It should be backward-compatible if the client and the server are using the same logic to sanitize/validate the attributes. This PR leverages the
sanitizeBlockAttributesAPI to achieve this, not sure if we should mark it as experimental at this stage though.How has this been tested?
