reduced_composition not on par with doc_string

Python version

Python 3.11

Pymatgen version

'2024.11.13'

Operating system version

MacOSX

Current behavior

From the docstring for reduced_composition:

@property
def reduced_composition(self) -> Self:
"""The reduced composition, i.e. amounts normalized by greatest common denominator.
 E.g. "Fe4 P4 O16".reduced_composition = "Fe P O4".
 """

I would expect to do just that, but Cs4 O4 turns into Cs2 O2 rather than Cs O. Unsure if its because some single element, for example:

Composition("O").reduced_composition # O2

Expected Behavior

I would expect that Cs4 O4 turns into Cs O rather than Cs2 O2. Unsure if its because some single element, for example:

Composition("O").reduced_composition # O2

Minimal example

from pymatgen.core import Composition
comp = Composition('Cs4 O4')
print(comp.reduced_composition) # prints out Cs2 O2, should be Cs O per doc string?
