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:

Commencez par exécuter l’exemple swarmchart fourni et comparer sa sortie avant et après fig2plotly(). Suivez la manière dont fig2plotly() traite l’entrée sz de swarmchart pour les trois séries. C’est terminé lorsque le graphique généré conserve des tailles de marqueur visiblement différentes pour les valeurs 5, 20 et 50.
