Dejavu renders HTML widgets as plain text

ankostis commented 1 year ago

With the following code in a jupyter notebook containing a single cell with these html elements:

from IPython.display as ipd
import ipywidgets as w

display(ipd.HTML("IPython <b>html</b>"))
display(w.HTML("Widget <i>html</i>"))

with (o := w.Output()):
  display(ipd.HTML("<html>Html in a manual <i>Output()</i> widget.</html>"))

display(o)

...and after converting the notebook to a html with this cmd:

jupyter dejavu --to=html exporttest.ipynb

... i get the html-code of the cell as plain text:
The expected content is this screenshot from the rendered notebook (identical to the voila dashboard):
Note that both IPython.core.display.HTML (a DisplayObject class) and ipywidgets.HTML (a widget) fail to render.

I think #1934 solves this

ankostis commented 1 year ago

It doesn't yet - #1934 needs to also make the same fix to share/templates/lab/base.html.j2.
