Plotly - multiple series plots with color axis cause error when trying to move panel

[mofojed]

Description

Steps to reproduce

1. Create a plotly figure with multiple series and plot types:

from plotly.subplots import make_subplots
import plotly.graph_objects as go
fig = make_subplots(rows=1, cols=2)
fig.add_trace(
    go.Scatter(x=[1, 2, 3], y=[4, 5, 6]),
    row=1, col=1)
fig.add_trace(
    go.Bar(x=[1, 2, 3], y=[4, 5, 6], marker=dict(color=[4, 5, 6], coloraxis="coloraxis")),
    row=1, col=2)
fig.update_layout(title_text="Side By Side Subplots", showlegend=False)

2. Click and drag the figure to place it somewhere else in the layout

Expected results
2. Plot should move

Actual results
2. Plot gets stuck, layout is broken:

Note - if I remove coloraxis="coloraxis" it seems to work okay.

I've filed an issue in plotly.js for this: plotly/plotly.js#6630

I've created a codepen that narrows the issue down to a coloraxis and autosizing: https://codepen.io/mofojed/pen/WNYNpBv
