Node is not rendered if visual metadata has undefined x and y values

[Mearman]

The following TS

export default await base
  .input({
    $metadata: {
      title: "Input",
      visual: {
        // x: 0,
        // y: 0,
        collapsed: true,
      },
    },
  }).to(base.output())
  .serialize({ title: "Foo" });

produces this JSON

{
  "title": "Foo",
  "edges": [
    {
      "from": "input-50",
      "to": "output-51",
      "out": "*",
      "in": ""
    }
  ],
  "nodes": [
    {
      "id": "input-50",
      "type": "input",
      "configuration": {},
      "metadata": {
        "title": "Input",
        "visual": {
          "collapsed": true
        }
      }
    },
    {
      "id": "output-51",
      "type": "output",
      "configuration": {}
    }
  ]
}

which is rendered like:

which when copied out of the editor yields:

{
  "title": "Foo",
  "metadata": {
    "comments": []
  },
  "edges": [
    {
      "from": "input-50",
      "to": "output-51",
      "out": "*",
      "in": ""
    }
  ],
  "nodes": [
    {
      "id": "input-50",
      "type": "input",
      "configuration": {},
      "metadata": {
        "title": "Input",
        "visual": {
          "x": null,
          "y": null,
          "collapsed": true
        }
      }
    },
    {
      "id": "output-51",
      "type": "output",
      "configuration": {},
      "metadata": {
        "visual": {
          "x": 60,
          "y": 0,
          "collapsed": false
        }
      }
    }
  ]
}

Which is then rendered without the Input node in the GUI.

So, there is probably an issue with the loading of the board, as the serialisation looks fine. But also the bullish values could be handled by BB Web

This was a fun one to track down!
