Add an option to set the opacity of markers in the legend

Can you kindly consider adding an option to set the opacity of legend markers? Currently, the opacities of the legend's markers are tied to the opacity values of the traces.

Plotly Version
plotly.js v2.35.2

Some scatter plots use a very low opacity (<0.10) to display the concentration of overlapping data points.

👇 This can result in imperceptible marker colors in the legend, as shown below:

I used a workaround to manually set the opacity of the scatterpts class using CSS.

/* current workaround */
.legendpoints .scatterpts {
  opacity: 1 !important;
}

Thank you for maintaining one of the best DataViz libraries! 👍

リンクされた CodePen を使用して、plotly.js で低い不透明度の散布図の凡例マーカーを再現し、.legendpoints .scatterpts ワークアラウンドの背後にある凡例マーカーの挙動を調査します。値によって凡例マーカーの不透明度をトレースの不透明度とは独立して制御するオプションを定義し、その後、凡例の外観とトレースのレンダリングの両方が正しいままであることを確認します。
