Bug report

Bug description:

Using the parameter end=" " in a print() causes the output to omit the first word for some reason

>>> print("Hi I am a bug", "Python 3.13.2", end=" ")
>>>  am a bug Python 3.13.2

This doesn't happen in v3.13.1 so it might be a regression

CPython versions tested on:

3.13

Operating systems tested on:

Windows

    @FurtadoPires Please read the original issue. Print is printing everything. But the 3+1=4 character prompt is being written over the first chars of the output instead of on a new, clean line.
