legend bug

[wadjih-bencheikh18]

when using function series under bar series the legend of this latter does not appear

 <Plot {...DEFAULT_PLOT_CONFIG}>
      <Legend {...props} labelStyle={{ cursor: 'hand' }} />
      <BarSeries
        data={data2}
        lineStyle={{
          stroke: 'green',
        }}
        label="Label Bar series"
      />
      <FunctionSeries
        getY={(x) => 5 * Math.sin(x) + 10}
        lineStyle={{
          stroke: 'brown',
        }}
        label="Label Function series"
      />
    </Plot>

but if we reverse it works correctly
