Description

bug P2 regression

Code example:

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

df = pd.DataFrame({
    'lat': np.random.uniform(chicago_lat - lat_range, chicago_lat + lat_range, 50),
    'lon': np.random.uniform(chicago_lon - lon_range, chicago_lon + lon_range, 50),
})

figure = go.Figure(
    go.Scattermap(
        lat=df['lat'],
        lon=df['lon'],
        mode='markers',
    )
)

figure.update_layout(map_bearing=90)
figure.show()

When I move the mouse over different locations, I cannot see the hover information for the location I am hovering over. Instead, it is stuck on a location at the edge of the map. This does not happen when map_bearing is set to 80, 70, 45. The screen recording below demonstrates the issue.
