Auto-indentation in python shell breaks copy-paste

Bug report

Bug description:

>>> def foo(x):
>>>         y = x + 1
>>>             z = 2 * y

The auto-indent feature in python 3.13.x shell breaks copy-paste of code on Windows.
Expected behavior: Copying properly formatted python code and pasting it into the shell works
Observed behavior: The auto-indenter adds additional indentation to every single line, effectively doubling the desired indentation, thus breaking the code

CPython versions tested on:

3.13

Operating systems tested on:

Windows

Might be the same issue as #129076

I think so, hence I'll close it as a duplicate.
