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:

Inizia eseguendo l'esempio swarmchart fornito e confrontandone l'output prima e dopo fig2plotly(). Traccia il modo in cui fig2plotly() gestisce l'input sz di swarmchart per le tre serie. Il lavoro è completato quando il grafico generato conserva dimensioni dei marker visibilmente diverse per i valori 5, 20 e 50.
