Bug report

Bug description:

When having the new genetics syntax type annotations on a function:

def bar[T](): ...

establishing a breakpoint returns the following message:

(Pdb) break bar
*** The specified object 'bar' is not a function or was not found along sys.path.

This also happens with temporary breakpoins tbreak. This was tested using Python versions from Debian official repositories. The failure appears in 3.13.0 and 3.12.6.

Analyzing with @asottile they point out that the following lines: Lib/pdb.py:121, Lib/pdb.py:141 may be causing this behavior.

This issue relates to #125884
