[BUG] show_dash() not rendering in VS Code/Jupyter with Dash 4.0.0

[arnoldjames98]

Describe the bug 🖍️

Upgrading to Dash 4.0.0 causes fig.show_dash() to fail within VS Code Jupyter notebooks on my macOS system. The cell executes and creates a blank vertical space, but no plot renders. FigureWidgetResampler(fig) still works so is currently a workaround.

Reproducing the bug 🔍

1. Using dash==4.0.0.
2. Open a Jupyter Notebook in VS Code on macOS.
3. Run the following minimal code:

import pandas as pd
import numpy as np
from plotly_resampler import FigureResampler
import plotly.graph_objects as go

fig = FigureResampler(go.Figure())
x = np.arange(1000)
y = np.random.randn(1000)
fig.add_trace(go.Scattergl(name='test'), hf_x=x, hf_y=y)
fig.show_dash()

Expected behavior 🔧

An interactive Dash application should render inline within the VS Code notebook cell output.

Environment information:

• OS: macOS
• Python environment: Poetry / VS Code Jupyter Extension
  • Python version: 3.11
  • plotly-resampler environment: VS Code Notebook
• plotly-resampler version: 0.11.0

We're seeing the same problem as well. We're transitioning to FigureWidgetResampler while this is pending a fix.

Same issue on my Windows machine. I could solve it by rolling back dash, ipykernel and plotly version:

dash==3.3.0
ipykernel<7
plotly==6.5.0
plotly-resampler==0.11.0
