Size variation not working using swarmchart

The input argument sz isn't changing marker's size when using swarmchart.

rng(1)
x1 = ones(1,100);
x2 = 2 * ones(1,100);
x3 = 3 * ones(1,100);
y1 = 2 * randn(1,100);
y2 = [randn(1,50) randn(1,50) + 4];
y3 = 5 * randn(1,100) + 5;

swarmchart(x1,y1,5)
hold on
swarmchart(x2,y2,20)
swarmchart(x3,y3,50)
hold off

fig2plotly();

The previous code should plot 3 different series with 3 different marker's size, however, they're all being plotted with the same size.

Expected and generated (https://chart-studio.plotly.com/~xarico10/323/#/) plot:

Examples on using the sz input argument on swarmchart() can be found on:

Empieza ejecutando el ejemplo de swarmchart proporcionado y comparando su salida antes y después de fig2plotly(). Rastrea cómo fig2plotly() gestiona la entrada sz de swarmchart para las tres series. Se considera terminado cuando el gráfico generado conserva tamaños de marcador visiblemente diferentes para los valores 5, 20 y 50.
