For some of my apps, I cache figures in as files via pickle. This works both for "pure matplotlib" as well as seaborn figures.

As of late, I am seeing an itertools depcreciation warning when storing sns plots this way:

import pickle
import seaborn as sns

tips = sns.load_dataset("tips")
ax = sns.boxplot(x="day", y="total_bill", data=tips)

pickle.dump(ax.get_figure(), open("temp.pkl", "wb"))

DeprecationWarning: Pickle, copy, and deepcopy support will be removed from itertools in Python 3.14.

This warning does not occur when storing pure matplotlib plots. My guess is that this storing technique will fail for sns plots with python >= 3.14. Is there a way to avoid this?

Versions:
sns: 0.13.2
plt: 3.10.1
