ipywidgets Cannot type `L` in Text and TextArea: captured by Jupyterlab

Description

The character L is captured by the JupyterLab interface when typing in an ipywidget Text, Textarea, Password.

Detected because Travo uses Password to enter credentials, and some of our 250 students had trouble authenticating because they had a L in their password which silently did not get inserted. That was tricky to analyse :-)

Reproduce

Launch a freshly installed jupyter lab with ipywidgets

mamba create -n test jupyterlab ipywidgets
conda activate test
jupyter lab

Open a notebook, and a Text or Textarea() in it:

import ipywidgets
ipywidgets.Text()

Input L in the text zone.

Expected: A L is inserted

Got: nothing is inserted; instead, cell line numbering is toggled for all cells

Context

/cc @SylvainCorlay : if someone on the QuantStack team would be available for resolving this issue, it would be a high priority item to insert in the contract.

I think this could have been introduced by https://github.com/jupyterlab/jupyterlab/pull/14740 in JupyterLab v4.0.5. A workaround might be downgrading to 4.0.4. Linking https://github.com/jupyterlab/jupyterlab/pull/14115 as we may want to test how this behaves after change to keyboard event bubbling.

Thanks @krassowski for investigating. I confirm that downgrading 4.0.4 fixes the problem and that it appears at 4.0.5.

Seems like an upstream bug in JLab. I'll leave this open for tracking purposes, until it's fixed.

@nthiery I think this issue has been fixed with https://github.com/jupyterlab/jupyterlab/pull/14115. Can you try again with jupyterlab 4.0.10 ?

Just tried with 4.0.11 and it works smoothly indeed. Thanks to all!
