[BUG]: Y-axis autorange stops working when updating the xaxes range for subplots with shared x-axes and y-axes

[CarlAndersson]

Description

Making a subplot figure with shared_xaxes = True, shared_yaxes=True and updating the figure to with an explicit xaxis_range resets the y-axes ranges to (-1, 4).

• This only happens of both the x-axes and y-axes are shared, and only when updating the x-axes range.
• It only happens if you actually have more than one row, and more than one column in the figure.
• Tried with numpy inputs and plain python lists - same result.

Steps to reproduce

import numpy as np
import plotly.graph_objects as go
from plotly.subplots import make_subplots

fig = make_subplots(rows=2, cols=2, shared_xaxes=True, shared_yaxes=True)
x = np.linspace(0, 100, 200)
y = 10 * x
fig.add_scatter(x=x, y=y, row=1, col=1)
fig.add_scatter(x=x, y=y, row=1, col=2)
fig.add_scatter(x=x, y=y, row=2, col=1)
fig.add_scatter(x=x, y=y, row=2, col=2)
fig.update_xaxes(range=(0, 100))
fig.show()

@CarlAndersson this does appear to be a bug in Plotly.js. I'll transfer the issue over to that repo so we can look at it.

In the meantime, I believe the issue is in how we detect the need to auto-set the range on the y axis when only the x axis is set. You should be able to work around this by setting the y axis behavior explicitly.

fig.update_xaxes(range=(0, 100))
fig.update_yaxes(autorange=True)

Yep, I can confirm that explicitly setting autorange=True on the yaxes is a viable workaround. Thanks for the quick response!
