Latex plot titles are not rendered in VS Code

Hi,

I try to rename my plot axis using latex titles, they are not rendered in my VS Code jupyter notebook, nor in an exported html using include_mathjax = 'cdn'.

fig = go.Figure(
    data=go.Scatter3d(x = [1,2,3],y=[2,3,1],z=[1,3,3]))
fig.update_layout(scene = dict(xaxis_title = r"$\lambda$"))
fig.show()

gives me:

The same expression in a markdown cell works:

$\lambda$

Using maplotlib works, as well.

I tried a workaround posted in #1740 using:

from IPython.display import display,HTML
display(HTML("""
<script type="text/javascript" async
  src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=config=TeX-AMS-MML_SVG">
</script>
"""))

without success.

Any help is appreciated!

VS Code Jupyter notebook と、include_mathjax = 'cdn' を指定してエクスポートした HTML で例を再現し、その後、プロットタイトルの挙動を、動作する Markdown セルの例と比較します。LaTeX の軸タイトルが、失敗した MathJax workaround なしで両方の環境に表示されれば、issue は解決です。
