showframe not working for scattergeo if geo.scope is set

Expect that when showframe=True that there's a border around the map.

# Create a sample dataframe
np.random.seed(42)  # For reproducibility

data_1041 = pd.DataFrame({
    'latitude': np.random.uniform(low=10.0, high=35.0, size=data_size),

Workaround:
Get rid of scope='north america', and the frame will appear with and without showframe defined

Commencez par exécuter la reproduction Scattergeo fournie et comparez la carte rendue avec et sans geo.scope défini sur "north america". Suivez ensuite le chemin de rendu de la frame geo dans plotly.js, puis vérifiez que showframe=True produit la bordure attendue lorsqu’un scope est configuré et que le workaround existant n’est plus nécessaire.
