Margins not updating correctly in pie chart after manual resizing

When dynamically updating a pie chart, I encountered an issue where the available space for the pie chart does not update properly after changing the plot size.

For my setup, the plot is rendered using Plotly in a React app. The plot state is managed using useState() and the layout updates are triggered via useEffect() whenever a user changes the settings object (for plot width, height, font, etc). The update is performed like this:

setPlot((prevPlot) => ({
  ...prevPlot,
  layout: {
    ...prevPlot.layout,
    width: displaySizes.width,
    height: displaySizes.height,
    margin: {
      ...prevPlot.layout.margin,
      t: settings.marginTop,
      b: settings.marginBottom,
      l: settings.marginLeft,
      r: settings.marginRight,
    },
    // other layout updates
  },
}));

Used versions are "plotly.js": "^3.0.0", "plotly.js-dist-min": "^3.0.1", "react-plotly.js": "^2.6.0".

Steps to reproduce the described bug:

1. Render a pie chart with segments [39,61]
2. Set the plot size to an incorrect size, e.g. width: 40, height: 255
3. Correct the plot size to valid values, e.g. width: 400, height: 255

Plot, before resizing:

Plot, after resizing as described:

The visible margins are now way larger than what is defined in the layout and much larger than necessary, since the pie chart could take up more space (like before). Changing the margins or plot size has no effect on the margins; only randomly increasing or decreasing the text size causes the plot to reset and render correctly.
It seems like the issue is related to the segment ratio: It only occurs when the pie segments are similar (e.g. [39, 61]), but not when they differ a lot (e.g. [10, 90]).

None of the approaches I came across online (such as Plotly.Plots.resize() or using the revision prop) solved this problem.

まず、plotly.js 3.0.x と react-plotly.js 2.6.0 を使用する React アプリで、[39,61] のセグメントを持つ円グラフを使って問題を再現します。幅を 40 から 400 に変更した後のレイアウト更新を追跡し、[10,90] のケースと比較します。完了の条件は、サイズ変更とマージンの更新によって、font-size の変更を必要とせずに円グラフで利用可能なスペースが再計算されることです。
