autosize not working as expected in plotly.offline.plot

The height of plots stored in html via plotly.offline.plot is set to 450px when height is not specified (at least in my test).

Example:

import numpy as np
import pandas as pd
import plotly
from plotly import graph_objs as go
from plotly.offline import plot

N = 1000
df = pd.DataFrame({
    't': np.random.random(N),
    'x': np.random.random(N),
    'y': np.random.random(N)
})

traces = [
    go.Scatter3d(
        x=df['x'],
        y=df['y'],
        z=df['t'],
        mode='markers',
        marker=dict(size=1)
    )
]

layout = go.Layout(
    autosize=True,
    scene=go.layout.Scene(
        xaxis=go.layout.scene.XAxis(title='X'),
        yaxis=go.layout.scene.YAxis(title='Y'),
        zaxis=go.layout.scene.ZAxis(title='Time'),
    )
)
fig = go.Figure(data=traces, layout=layout)

filename = f"demo.html"
plotly.offline.plot(fig, filename=filename, auto_open=False)

The picture below shows the entire browser page in Firefox 66.0.3 on macOS High Sierra 10.13.6. The file looks the same in Chrome 73.0.3683.103. I am using plotly 3.8.0 on Python 3.7.

@jonmmease Confirmed! The problem disappears with the build you linked! Thanks for the quick response!

@marcotama and @ijustmadethisforplotly, could you give the dev build in #1525 a try and confirm that it takes care of the problems you’re seeing?

Installation instructions are in https://github.com/plotly/plotly.py/pull/1525#issuecomment-484235115. Thanks!
