Scatter plot filltozeroy fails on multi-signed values

Apologies if this is a duplicate issue, but a similar one could not be found.

For scatter plot data containing both positive and negative values, fill="tozeroy" does not correctly fill under the trace as I expected. I'm not sure if this is a future feature or current bug, but I couldn't find documentation which states that scatter plot filling for both negative and positive values was not supported.

plotly.__version__

4.5.4

from plotly import graph_objects as go
import numpy as np

x = np.linspace(0, 100)
y = np.random.rand(100) - 0.5

fig = go.Figure(data=go.Scattergl(x=x, y=y, fill="tozeroy"))
fig.show()

Start by running the provided Python reproduction with plotly 4.5.4 and inspect how go.Scattergl handles fill="tozeroy" for mixed positive and negative y values. Done means the trace fills correctly to zero on both sides of the axis, with coverage for the reported case.
