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:

記載されている Plotly 4.0.0 および 4.1.0 のバージョンを使用して、提供された図を JupyterLab と Jupyter Notebook で再現します。まず、レンダリングされた LaTeX タイトルと画像が引き伸ばされる挙動を比較し、次に issue に表示されているターミナル出力を確認します。LaTeX タイトルが一貫してレンダリングされ、セッションを再起動した後に図が引き伸ばされなくなれば完了です。
