[HELP] Markers disappear when I try to plot more than 20 points with go.Scatter on Jupyter Notebook

📊 Plotly Python

As the title say, if I plot more than 20 points with plotly.graph_objects.Scatter, the marks of the graph disappear. I’ve set up the following minimum reproducible example

import numpy as np

import plotly
import plotly.express as px
import plotly.graph_objects as go

print(plotly.__version__, '\n-------')

def plot(n):
    
    fig = go.Figure()
    fig.update_layout(width=500, height=300)
    
    fig.add_trace(go.Scatter(x=np.arange(n), y=np.arange(n)))
    
    fig.show()
    
for n in [10, 15, 19, 20, 30, 100]:
    print(n)
    plot(n)

And the outputs are:

mre_1
mre_11739×1545 46.3 KB

mre_2
mre_21741×1663 44.7 KB

As you can see, for n >= 20, the scatter points disappear. I tried without setting the width and height of the Figure, and without defining marks in go.Scatter, but the problem persists. What is happening here?
