Horizontal legend entrywidth does not adjust to font size on initial render

When initially rendering the component, when set to orientation "h", the legend entries do not adjust their size correctly based on the font size set in the layout.

Example:

`
export const Test = (): ReactElement => {

  const data : Data[] =[
      {
          x: [1, 2, 3],
          y: [2, 6, 3],
          name: "my example scatter chart",
          type: 'scatter',
          mode: 'lines+markers',
          marker: {color: 'red'},
      },
      {type: 'bar', name:"my example bar chart", x: [1, 2, 3], y: [2, 5, 3]},
  ]

  const layout = {
      width: 1350,
      height: 950,
      hoverlabel: {
          bgcolor: "#555555",
          font: {
              family: "Open Sans",
              size: 14
          }
      },
      legend: {
          x: 0.25,
          y: -0.35,
          orientation: "h" as any,
          font: {
              family: 'Open Sans',
              size: 24,
              color: '#555555'
          },
          entrywidth:0,
      },
      xaxis: {
          showline: false,
          zeroline: false,
          title: {
              text: 'x',
              font: {
                  family: 'Open Sans',
                  size: 14,
                  color: '#555555'
              }
          },
      },
      yaxis: {
          showline: false,
          zeroline: false,
          title: {
              text: 'y',
              font: {
                  family: 'Open Sans',
                  size: 14,
                  color: '#555555'
              }
          }
      }
  }


  return (<Plot
      layout={layout}
      data={data}
  />)

}
`

If I adjust the font size property of the layout object after the initial render, it corrects itself.

Any guidance or help would be greatly appreciated.

Start with the initial render path for the component and the horizontal legend sizing behavior described in the example. Reproduce the chart with orientation "h" and a 24px legend font, then compare it with the result after changing the font size; done means entry widths match the configured font on the initial render.
