Python Debugger F11 and sometimes F10 appear broken

[fierval]

Type: Bug

In a Python file, try stepping into a method hitting F11. The indicator simply blinks and nothing happens. Only F5 appears to work.

Additionally, even though just-my-code is set to "false", breakpoints in packages are ignored.

Here trying to repeatedly hit F11 and F10:

Downgraded to 1.89.1 works fine.

Looks like you are stepping through module.py which is a hidden library file. Not sure whether it is supposed to be opening the editor for module.py or if this is expected for this scenario.

Could you open this on the vscode-python repo? It might help to include an example of what you see different in 1.89

It happens on ANY file, I just posted an example for visual clarity. I'll re-open in the other repo.
