Problem statement

Bug summary

I have code that executes:

import matplotlib.pyplot as plt
the_rc = plt.style.library["seaborn-colorblind"]

Using version 3.4.3 of matplotlib, this works fine. I recently installed my code on a machine with matplotlib version 3.6.1 and upon importing my code, this generated a key error for line the_rc = plt.style.library["seaborn-colorblind"] saying "seaborn-colorblind" was a bad key.

Code for reproduction

python
import matplotlib.pyplot as plt
the_rc = plt.style.library["seaborn-colorblind"]

Actual outcome

Traceback (most recent call last):
KeyError: 'seaborn-colorblind'

Expected outcome

seaborn-colorblind should be set as the matplotlib library style and I should be able to continue plotting with that style.
