v7 horizontal scroll bar absent in Firefox

[liquidcarbon]

Firefox - no way to scroll to the last columns

Edge

Thanks for opening this issue @liquidcarbon! This has been noted in jupyterlab/jupyterlab#14625 and will likely be resolved in Notebook 7 once Jupyterlab is updated.

As mentioned in ticket #14625 of jupyterlab for googlers arriving here:

Workaround to show the scrollbars from within a Notebook cell:

from IPython.display import display, HTML
display(HTML("<style>.jp-OutputArea-output {display:flex}</style>"))

I can confirm @liquidcarbon 's observations:

• edge shows horizontal bars
• chrome shows them as well
• firefox doesn't

When you see this issue with Notebook v7.0.5+:

1. Can you reproduce in a clean environment with a fresh pip install?
2. What version of Firefox you use?
3. Can you shift + right-click over the data frame output and select "inspect" and create a screenshot like below (with jp-OutputArea-output selected and CSS rules visible):

I just installed a new environment with this command:

mamba create -n v7bar python=3.11 notebook ipywidgets pandas

This installed v7.0.6 of notebook.

I then started the notebook:

conda activate v7bar
jupyter notebook

I then proceeded with this cell:

import numpy as np
import pandas as pd
df = pd.DataFrame(np.arange(100))
with pd.option_context('display.max_columns',100):
    display(df.T)

And ... I do have a scrollbar.

Ok, so I'm now off investigating what is different between the 2 environments.
FYI my screenshot resembles yours:

And this is in the other notebook where I don't have the scrollbar:
