fig.add_vrect() items do not hide when clicking on grouped legend if showlegend=False

[pcubillos]

Hi,

Here's a reproducible example below. Clicking on the legend group does not hide the second vrect (unlike for fig.add_trace(go.Scatter()) calls). I tried it on versions 5.23.0 and 5.19.0.

import plotly.graph_objects as go

fig = go.Figure()

fig.add_vrect(
    x0=1.0, x1=3.0,
    fillcolor="LightSalmon", opacity=0.3,
    layer="below", line_width=0,
    legendgrouptitle_text="Saturation",
    legendgroup='saturation',
    name='partial',
    showlegend=True,
)

fig.add_vrect(
    x0=3.5, x1=4.5,
    fillcolor="LightSalmon", opacity=0.3,
    layer="below", line_width=0,
    legendgroup='saturation',
    name='partial 2',
    showlegend=False,
)

fig.show()
