Bug code:

import plotly.graph_objects as go

fig.add_shape(
    type="line",
    xref="x",
    yref="y",
    x0=4,
    y0=0,
    x1=8,
    y1=1,
    line=dict(
        color="LightSeaGreen",
        width=3,
    ),
    legendgroup="group",  # this can be any string, not just "group"
    name="first legend group",
    showlegend=True,
)
fig.add_shape(
    type="line",
    xref="paper",
    yref="paper",
    x0=0,
    y0=0,
    x1=0.5,
    y1=0.5,
    line=dict(
        color="DarkOrange",
        width=3,
    ),
    legendgroup="group",  # this can be any string, not just "group"
    name="first legend group B",
    showlegend=False,
)

fig.show()

Reference:
https://plotly.com/python/legend/#grouped-legend-items Says: You can also hide entries in grouped legends, preserving the grouped show/hide behaviour. This is what Plotly Express does with its legends.
