When editing the layout object after it was sent it to `Plotly.newPlot`, it causes an error log `Uncaught container is not an object`. Seems only for non-objects that causes it: ``` var layout = { title: "title", margin: { l: 30, r: 50, t: 30, b: 10 } }; Plotly.newPlot('contourDiv', data, layout, {displayModeBar: false}); console.log(layout) layout.margin = {} -> It works layout.title = "edit title" -> Causes the error Plotly.update('contourDiv', data, layout) ``` Before version `1.43.0` the above code works. https://codepen.io/poldz123/pen/pqNBzj?editors=0010
