python-nav-forward-defun doesn't work properly in python-ts-mode, for

example with this file:

https://raw.githubusercontent.com/timlod/onset-fingerprinting/6c8f9bd3b82398c9af3519036e0d5a550ad3bae7/onset_fingerprinting/data.py

Specifically, at some point it will stop navigating, even though there

are still function definitions to traverse (other times I saw it skipped

some definitions before stopping altogether). I noticed that this

usually happens after some point in the buffer, but I haven't been able

to nail it down exactly. My hunch is that it could be related to

decorators (e.g. @classmethod) or type hints, or both.

It does work properly using just python-mode. This is tested using

`emacs -q`, so this bug persists just on a clean Emacs 29.3.

I checked previous reports and believe this is probably related to

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=60856, which isn't fixed yet.
