Feature Request: Add vertical spacing option between plot and rangeslider

Hi Plotly team ,

I'm working with rangeslider in a dual-axis layout (xaxis + xaxis2, yaxis2), and I’d like to request a feature that allows more control over the vertical spacing between the plot area and the rangeslider.

In the current setup, the rangeslider always appears directly below the main plot and sometimes the labels are inside the rangeslider.

The definition of the layout is:

function staticLayout(): object {
  
  return {
    margin: {l: 70, r: 20, t: 10, b: 20},
    showlegend: true,
    legend: {
      orientation: 'h',
      x: 0,
      y: 1.02,
      yanchor: 'bottom',
    },
    xaxis: {
      domain: [0.0, 1.0],
      anchor: 'y',     
      side: 'bottom',    
      title: {
        text: 'Time (s)',
        standoff: 15
      },
      automargin: true,
      rangeslider: {
        visible: true,
        thickness: 0.07,
        bgcolor: "#f5f5f5",
        bordercolor: "black",
        borderwidth: 1,
      },
      showticklabels: false,
      showgrid: false,
      zeroline: false,
      fixedrange: true,
    },
    yaxis: {
      visible: false,
      showticklabels: false,
      showgrid: false,
      zeroline: false,
      showline: false,
      overlaying: 'y2',
    },
    xaxis2: {
      anchor: 'y2',      
      side: 'bottom',    
      // type: 'log',
      ticklabelposition: 'outside',
    },
    yaxis2: {
      anchor: 'x2',
      zeroline: false,
      showticklabels: true,
      ticklabelposition: 'outside',
    }
  };
}

How can I fix the spacing?

まず、xaxis.rangeslider を使った、提示された2軸レイアウトと、スクリーンショットにあるラベルの重なり方を再現します。次に、プロットと rangeslider の間隔がどこで決まるかを追跡し、要求された間隔オプションを定義して、例でプロットと rangeslider が分離され、ラベルがその内部に配置されないことを検証します。
