My custom defined signal handler gets reverted in jupyter when I run the very next cell. This doesn't appear to be the case when running python and ipython.

It's dirty, but you could do something like
try:
# prevent Jupyter from reverting the signal handler before executing a cell:
# https://github.com/ipython/ipykernel/blob/14c385318/ipykernel/kernelbase.py#L425-L432
kernel = get_ipython().kernel # type:ignore [name-defined]
kernel.pre_handler_hook = lambda: None
kernel.post_handler_hook = lambda: None
except NameError:
# normal Python environment
pass
where you set your signal handler.
