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.

Plotly 5.18.0 を使用して 2 つの Python 例を再現し、Scattergl トレースとその順序に焦点を当てます。fill="tonexty" に対する Scattergl のレンダリングパスを追跡します。別の Scattergl トレースが 2 つのトレースに先行すると塗りつぶし領域が表示され、順序を変更しても正しい状態が保たれれば完了です。
