Scattergl does not fill (`tonexty`) if another Scattergl trace is present

When attempting to fill the area between two lines using Scattergl, no filled area is showing up when another Scattergl trace is present before the two traces I'm trying to fill between. See the example below.

I'm not sure if this issue is related to some of the other issues posted about Scattergl and filling but none of those seem to mention the filled area not showing up, so I figured I'd post a new issue.

plotly version 5.18.0

Not working

This example shows what i mean:

import plotly.graph_objects as go
import numpy as np

upper_trace = go.Scattergl(
    x=np.arange(10),
    y=np.ones(10),
    mode="lines",
    line_color="blue",
    fill="tonexty",
    legendgroup="area",
)
lower_trace = go.Scattergl(
    x=np.arange(10),
    y=-np.ones(10),
    mode="lines",
    line_color="blue",
    fill="tonexty",
    legendgroup="area",
    showlegend=False,
)
other = go.Scattergl(
    x=np.arange(10),
    y=2 * np.ones(10),
    mode="lines+markers",
    line_color="red",
)

go.Figure([other, upper_trace, lower_trace])

Output:

Working

go.Figure([upper_trace, lower_trace, other])

Thanks in advance for taking a look.

Reproduisez les deux exemples Python avec Plotly 5.18.0, en vous concentrant sur les traces Scattergl et leur ordre. Suivez le chemin de rendu de Scattergl pour fill="tonexty" ; le travail est terminé lorsque la zone remplie apparaît lorsqu’une autre trace Scattergl précède les deux traces et reste correcte lorsque l’ordre est modifié.
