Bug Report: hovertemplate in go.Surface doesn't work properly

The hovertemplate for go.Surface doesn't work properly, it can't display the user defined customdata nor 'text', it will only display the plain text as "cost: %{text}".
Of course, I have also tried that it works well for go.Scatter and go. Scatter3d.

Check the following code, you can see the bug:

import plotly.graph_objects as go
import numpy as np

# Example data for the trajectory
x_traj = [0, 1, 2, 3, 4, 5]  # X-coordinates
y_traj = [0, 1, 4, 9, 16, 25]  # Y-coordinates
z_traj = [0, 1, 8, 27, 64, 125]  # Z-coordinates

# Example data for the contour
x = np.linspace(-10, 10, 100)
y = np.linspace(-10, 10, 100)
X, Y = np.meshgrid(x, y)
Z = np.sin(np.sqrt(X**2 + Y**2))  # Example Z values

# Create a 3D plot
fig = go.Figure()

# Add the 3D trajectory
fig.add_trace(go.Scatter3d(
    x=x_traj,
    y=y_traj,
    z=z_traj,
    text=[1,2,3,4,5,6],
    mode='lines+markers',  # Use 'lines' for trajectory and 'markers' for points
    line=dict(color='blue', width=2),  # Customize line color and width
    marker=dict(size=5, color='red'),  # Customize marker size and color
    hovertemplate="x: %{x:.2f}<br>y: %{y:.2f}<br>index: %{text}<br> <extra></extra>",
))

# Add the contour on Z=5 plane
fig.add_trace(go.Surface(
    x=x,
    y=y,
    z=np.full_like(Z, 5),  # Set Z=5 for the contour plane
    surfacecolor=Z,  # Use Z values for the contour colors
    text=Z,
    colorscale="Viridis",
    showscale=True,
    contours=dict(
        z=dict(
            show=True,
            start=-1,  # Minimum contour value
            end=1,     # Maximum contour value
            size=0.2,  # Step size between contours
            usecolormap=True,
            project_z=True  # Project contours onto the Z plane
        )
    ),
    opacity=0.7,  # Make the contour plane semi-transparent
    # hoverinfo="x+y+text", # works well
    hovertemplate="x: %{x:.2f}<br>y: %{y:.2f}<br>cost: %{text}<br> <extra></extra>", # doesn't work

))

# Update layout for better visualization
fig.update_layout(
    title="3D Trajectory with Contour on Z=5 Plane",
    scene=dict(
        xaxis_title="X Axis",
        yaxis_title="Y Axis",
        zaxis_title="Z Axis"
    ),
    width=800,
    height=600
)

# Show the plot
fig.show()

Esegui la riproduzione Python fornita con go.Surface e confronta il suo comportamento di hovertemplate con quello dell'esempio funzionante go.Scatter3d. Inizia tracciando il modo in cui go.Surface gestisce text e customdata per l'output dell'hover. Il lavoro è completo quando l'etichetta hover della surface visualizza il testo definito dall'utente o customdata invece del segnaposto letterale %{text}.
