Describe the issue:

https://github.com/user-attachments/assets/263d8c75-9987-4517-ba56-ed01a07d66bb

Plotnine plots are reprinted and throw an error every time any Python code is executed:

/Users/thomasmock/.pyenv/versions/3.12.0/lib/python3.12/pprint.py:629: FutureWarning: Using repr(plot) to draw and show the plot figure is deprecated and will be removed in a future version. Use plot.show().

Same error with plot.show()

Steps to reproduce the issue:

Run the following Python script via console and then execute 1+1 in the console or any other code.

import pandas as pd
import numpy as np
from plotnine import ggplot, aes, geom_point, geom_smooth, theme_minimal, labs

# Create a sample dataset
np.random.seed(42)
data = pd.DataFrame({
    'x': np.random.rand(100) * 10,
    'y': np.random.rand(100) * 10 + np.random.rand(100) * 5
})

# Create the plot
plot = (
    ggplot(data, aes('x', 'y')) +
    geom_point(color='blue', alpha=0.6) +
    geom_smooth(method='lm', color='red', se=True) +
    theme_minimal() +
    labs(title='Basic Scatter Plot with Trend Line',
         x='X-axis', y='Y-axis')
)

# Display the plot
print(plot)

Expected or desired behavior:

No warning/error and no reprinting unless requested.

Were there any error messages in the UI, Output panel, or Developer Tools console?

It does seem very similar!
