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?

首先，使用 xaxis.rangeslider 复现所提供的双轴布局以及截图中的标签重叠行为。跟踪绘图与 rangeslider 之间的间距在哪里确定，然后定义所请求的间距选项，并验证示例能够将绘图与 rangeslider 分隔开，同时不会将标签放置在其中。
