Incorrect stack traceback when try except finally is used in jupyter notebooks with pandas

Description

The stack traceback of some errors is displayed incorrectly. Below are two examples of an incorrect stacktrace and correct stacktrace. The incorrect one creates a pandas dataframe in a faulty manner, raising an exception, its stacktrace points to a command in the finally block instead of the pandas dataframe creation which is the actual issue.

The correct example shows how a non-existing key of a dictionary is called, its stacktrace does not point to a statement in the finally block but rather points to the line that actually causes the issue.

Some things i've tried or noticed:

* the correct example contains hyperlinks to each code-line, while the incorrect one doesn't, maybe this is a hint to the cause. I therefore included the stacktrace of both examples in raw text as well as html.

* running the'incorrect stacktrace' example in pure python (.py file) results in a **correct** stacktrace

* this issue occurs when hosting jupyter notebooks locally, but also in VSCode notebooks using the ipykernel

* Thinking that C-code extensions of Python could be a potential source, I also tried raising errors using torch (torch.tensor('invalid_type') but this results in a correct stacktrace.

* aside of torch i also tried incorrectly initiating classes with other packages, this also lead to a correct stacktrace

Context

This occurs in the browser with notebook 7.0.7, but also in VSCode notebooks with ipykernel 6.29.2

* Operating System and version: macOS 14.2

* Browser and version: Firefox 122.0.1 though this shouldn't matter as the issue also occurs in VSCode
