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.

Reproduziere die beiden Python-Beispiele mit Plotly 5.18.0 und konzentriere dich auf die Scattergl-Traces und ihre Reihenfolge. Verfolge den Scattergl-Rendering-Pfad für fill="tonexty"; als erledigt gilt die Aufgabe, wenn die gefüllte Fläche erscheint, sobald ein weiterer Scattergl-Trace den beiden Traces vorausgeht, und korrekt bleibt, wenn die Reihenfolge geändert wird.
