comet() not working correctly

[xarico10]

When using comet() to display a comet plot of the data specified in y versus the index of each value (a comet is an animation of a marker (head) and a line (tail) tracing a growing line over the data points) a single-point scatter plot is printed.

t = 0:pi/100:2*pi;
y = sin(t);
x = cos(t);
comet(x,y)

fig2plotly(gcf, 'offline', false);

Expected animation and generated (https://chart-studio.plotly.com/~xarico10/837/#plot) plot:
