Might be a bit late to the party but this is what I got to make it work:

function fav_plugin_id_render($block_content, $block)
{
    if ($block['blockName'] === 'core/shortcode') {
        $block_content = str_replace("{{post_id}}", get_the_ID(), $block_content);
    }
    return $block_content;
}
add_filter('render_block', 'fav_plugin_id_render', 10, 2);

And so my shortcodes in the Query Loops become:

[favorite_button post_id="{{post_id}}"]

Found the idea from: https://wordpress.stackexchange.com/questions/417823/get-the-id-retrieves-same-id-on-gutenbergs-query-loop

I did some digging and you are right in that Divi 3 stops it working.

Ignore my above advice. Nothing of those will work at the moment.
