Figure does not display LaTeX expressions in JupyterLab and Jupyter Notebook

There is an issue with rendering LaTeX titles in JupyterLab:

fig = go.Figure()
fig.add_scatter(y=[1,3,2], mode='lines+markers')
fig.layout.update(title='$\\text{Negative Log of Estimated Survivor Function}$', 
                  xaxis_title='$t$', yaxis_title='$-log(S(t))$',
                  height=600)
fig.show()

Does not actually display the titles:

And this is strange as earlier today it did work fine.

I have encountered other anomalies in JupyterLab, such as after restarting the session, one image elongates and stays like that.
Does not happen every time though.

Here it is:

Sometimes it elongates and stays like that:

UPDATE 1:

I've just updated to 4.1.0 and now the LaTeX titles are displayed. But, the mentioned anomaly is still there.

UPDATE 2:

I have opened the notebook today again and the title disappears.

If it is of any help. here is what is displayed in the terminal:

使用所述的 Plotly 4.0.0 和 4.1.0 版本，在 JupyterLab 和 Jupyter Notebook 中复现所提供的图。首先比较渲染后的 LaTeX 标题和图像拉伸行为，然后查看 issue 中显示的终端输出。当 LaTeX 标题能够一致地渲染，并且重启会话后图不再拉伸时，即表示完成。
