Multiple legends in horizontal mode overlap chart on resize from a narrow viewport to a wide one

I am having troubles when changing from portrait mode to landscape mode as the legends overlap the x axis ticks or the chart itself.

Here is the reproducible example: https://codepen.io/bleah1/full/ZEMGVpY

Please use Inspect tools and either make the viewport narrow and then pull pretty fast to make it wide again or just go to mobile view and switch from portrait to landscape.

The legends remain in the same place when resizing from a narrow viewport to a wider one.

This behavior is not as bad on PC, because you can resize again and everything falls into place, but on mobile you can't resize the viewport/window, you can only refresh and I can't use it as it is now.

The code is pretty basic:

const plotDiv = document.getElementById('plot');
const traces = [
	{x: [1,2,3], y: [2,1,4], stackgroup: 'one'},
	{x: [1,2,3], y: [1,1,2], stackgroup: 'one'},
	{x: [1,2,3], y: [3,0,2], stackgroup: 'one'},
	{x: [1,2,3], y: [4,3,2], stackgroup: 'one'},
	{x: [1,2,3], y: [5,5,2], stackgroup: 'one'},
];

const layout = {
      showlegend: true,
      legend: {
        x: 0,
        // y: 1,
        orientation: "h",
        traceorder: "normal",
        yanchor: "top",
      },
      autosize: true,
      margin: { pad: 10, b: 10, l: 40, r: 40, t: 80 },  
}

const config = {
  responsive: true 
}

Plotly.newPlot('myDiv', traces, layout, config);

リンクされた CodePen の再現を起点に、plotly.js における凡例の水平方向の配置に関するレスポンシブなリサイズ経路を調査します。狭い状態から広い状態へのリサイズとリフレッシュを比較し、その後、viewport の変更後に凡例が x 軸の目盛りやチャートと重ならなくなっていることを確認します。
