Describe the bug
I would like to appliy the viewbox url parameter to embed.diagrams.net to show the full diagram.

To Reproduce
Steps to reproduce the behavior:
Use the example html code posted here:
https://stackoverflow.com/questions/79210639/how-to-set-viewbox-for-embed-diagrams-net-draw-io

Expected behavior

• The pan and zoom should be adapted to the specified view box.
  viewbox={"x":0,"y":0,"width":1000,"height":1000}
• The pan and zoom should be kept, even when running layout actions.
• Or there should be an action to update pan and zoom after running layout actions, e. g.

const iframe = document.getElementById('embedDiagram');
const config = {
    action: 'configure',
    config: {
        viewbox: { x: 0, y: 0, width: 1000, height: 1000 },
        pan: true,
        zoom: true
    }
};
iframe.contentWindow.postMessage(JSON.stringify(config), '*');

• If the viewbox url argument is not supported by embed.diagrams.net, this should be clarified in the documentation.
