Plotly python: force axis limits (range)

Question

Documentation of plotly says, with parameter range we can set the limits of the axis, for example range = [0, 10] sets the axis minimum to 0 and maximum to 10. According to docs, it can be used under figure, layout, scene or xaxis. Indeed Scatter and Layout accepts xaxis and yaxis arguments, which are either dicts or plotly.graph_objs.XAxis objects, and there it is possible to supply a range value. However, with trying all the variations I can imagine, it apparently fails to set the limits. In addition, the first subplot appears to be below the others. See the minimum working example below, which can be run in any Jupyter notebook.

Bonus question: why fill argument at Scatter fails to set the fill color of the dots?

It looks like it's working as expected in plotly=5.1.0.

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

fig = make_subplots(rows=2, cols=2, subplot_titles=sorted(data.keys()))
for i, name in enumerate(sorted(data.keys())):
    sub = data[name]
    fig.add_trace(
        go.Scatter(
            x = sub['x'], 
            y = sub['y'],
            mode = 'markers',
            marker = dict(
                size = sub['s'],
                sizemode = 'area',
                sizeref = 0.0001,
            ),
            name = name,
            showlegend = False,
        ),
        row = i // 2 + 1,
        col = (i % 2) + 1,        
    )
fig.update_xaxes(range=[0, 9])
fig.update_yaxes(range=[13, 60])  
fig
