Missing colorscales in ui buttons

In the following code I created a simple plot with a dropdown menu where each button is expected to modify the colorscale. However, some of these don't seem to work properly and when the corresponding button is clicked, a default colorscale is applied instead.

import plotly.graph_objects as go
import numpy as np

# Generate sample data
np.random.seed(42)
x = np.random.rand(100)
y = np.random.rand(100)
z = np.sqrt(x**2 + y**2)

# Available colormaps
colorscales = ['Viridis', 'Cividis', 'Plasma', 'Inferno', 'Magma']

# Create the initial figure with one colorscale
scatter = go.Scatter(
    x=x,
    y=y,
    mode='markers',
    marker=dict(
        size=10,
        color=z,
        colorscale=colorscales[0],
        colorbar=dict(title='Value'),
        showscale=True
    )
)

fig = go.Figure(data=[scatter])

# Add dropdown menu
fig.update_layout(
    updatemenus=[
        dict(
            buttons=[
                dict(
                    label=scale,
                    method='restyle',
                    args=[{'marker.colorscale': [scale]}]
                )
                for scale in colorscales
            ],
            direction='down',
            showactive=True,
            x=1.1,
            y=1
        )
    ],
    title="Scatter Plot with Colormap Dropdown",
    xaxis_title="X",
    yaxis_title="Y"
)

fig.show()

In this plot only 'Viridis' and 'Cividis' colorscales are supported. More in general it seems to me that the only supported ones are those defined in plotly.colors.plotlyjs (only the non-reversed ones).

Start by running the provided Python reproduction and compare the dropdown behavior with the names available in plotly.colors.plotlyjs. Trace how the Plotly Python figure serializes colorscale values for the buttons; done means the listed colorscales are accepted and applied consistently when selected.
