White space no longer dynamic after adjusting range of axis in Plotly

Question

When item in the legend is toggled off, the active datapoints will take up the freed space in the plot. However, if the y-axis range has been adjusted, the space remains empty. How to fix?

import plotly.graph_objects as go
import pandas as pd
import numpy as np

np.random.seed(42)
df = pd.DataFrame({
    'red': np.random.randn(50),
    'blue': np.random.randn(50) + 2,
    'green': np.random.randn(50) + 1, 
    'orange':np.random.randn(50) + 3, 
})

fig = go.Figure()
for i in df.columns:
    fig.add_trace(go.Scatter(
            x=df[i], 
            y=[i] * df[i].shape[0],
            name=i,
            mode='markers',
            marker_color= 'blue' if 'blue' in i else 'green' if 'green' in i else 'red' if 'red' in i else 'orange',
            legendgroup=i,
            showlegend=True
        ))
fig.update_layout(legend_traceorder='reversed')
fig.show() # if one item in the legend is toggled off, all space will be redistributed to displayed data points

# after adjusting range, space will remain empty when toggled off some data
fig.update_layout(height=800) # to maximize the impact the issue 
fig.update_yaxes(range=[-0.5, len(df.columns)-0.5])
fig.show()
