Annotated heatmap with plotly not working as it should

I’m new to Datalore, so hopefully this is an easy fix.

I’m trying to create an annotated heatmap with plotly, but the annotations don’t show up in Datalore. When I run the exact same code in Jupyter notebook it works as it should. I even tried the plotly documentation code on both Datalore and Jupyter:

import as px

z = [[.1, .3, .5, .7, .9],
     [1, .8, .6, .4, .2],
     [.2, 0, .5, .7, .9],
     [.9, .8, .4, .2, 0],
     [.3, .4, .5, .7, 1]]

fig = px.imshow(z, text_auto=True)

and again, it shows the numbers within each cell on Jupyter but not on Datalore.
I updated the plotly version on Datalore to the latest 5.14, still no success. Can anyone enlighten me as to what the issue might be and how to fix it?
