Figure does not display LaTeX title

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.

Details

Plotly version: 4.0.0

Ubuntu 18.04.2

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:

I can replicate the JupyterLab problem on my end also. The issue is likely to be within the interaction between the way jupyterlab_plotly extension renders Plotly.js figures within JupyterLab, and these problems tend to be pretty hard to debug but if you want to give it a shot, the source for the extension is here: https://github.com/plotly/plotly.py/tree/master/packages/javascript/jupyterlab-plotly

I found a solution that worked for me in the help documentation, changing the default renderer. I had the issue on multiple browsers. (https://plotly.com/python/renderers/)

1. The jupyterlab-plotly extension must be installed in the current environment. For conda, this is conda install -c conda-forge jupyterlab-plotly-extension.

2. Check the available renderers and ensure jupyterlab is available. import plotly.io as pio pio.renderers

Renderers configuration

Default renderer: 'jupyterlab'
Available renderers:
    ['plotly_mimetype', 'jupyterlab', 'nteract', 'vscode',
     'notebook', 'notebook_connected', 'kaggle', 'azure', 'colab',
     'cocalc', 'databricks', 'json', 'png', 'jpeg', 'jpg', 'svg',
     'pdf', 'browser', 'firefox', 'chrome', 'chromium', 'iframe',
     'iframe_connected', 'sphinx_gallery', 'sphinx_gallery_png']

1. Set the default renderer to jupyterlab. pio.renderers.default = ‘jupyterlab’
