Resolves #19866

What does this implement/fix? Explain your changes.

Running the following in jupyter lab:

%config InlineBackend.figure_format = 'retina'

from sklearn.datasets import make_classification
from sklearn.tree import DecisionTreeClassifier, plot_tree
import matplotlib.pyplot as plt

X, y = make_classification(random_state=0)
clf = DecisionTreeClassifier(max_depth=2, random_state=0)
clf.fit(X, y)

fig, ax = plt.subplots()
_ = plot_tree(clf, ax=ax)

On main:
