Plotly subplots using fig objects instead of traces

[pjadzinsky]

Hi
Any idea why these images don’t look the same size?

import ipywidgets as ipw
from plotly import express as px
import numpy as np
import plotly.graph_objects as go

fig = px.imshow(np.random.rand(3,3))
fig.update_layout(coloraxis_showscale=False)
fig.update_xaxes(showticklabels=False)
fig.update_yaxes(showticklabels=False)
fig = go.FigureWidget(fig)
ipw.HBox([fig, fig, fig])
