Color variation not working using swarmchart

The input argument c isn't changing marker's color 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,'red')
hold on
swarmchart(x2,y2,'green')
swarmchart(x3,y3,'blue')
hold off

fig2plotly();

The previous code should plot 3 different series with 3 different marker's color (red, green and blue), however, they're all being plotted with the default plotly colors.

Expected and generated (https://chart-studio.plotly.com/~xarico10/329/#/) plot:

Comienza ejecutando el ejemplo de MATLAB con tres llamadas a swarmchart() y fig2plotly(); después, sigue el punto de entrada de conversión de fig2plotly() para los colores de los marcadores de swarmchart(). Se considera terminado cuando la figura de Plotly exportada conserva los colores rojo, verde y azul de los marcadores mostrados en el issue.
