shapely: minimum_rotated_rectangle is incorrect in 2.0.0

Expected behavior and actual behavior.

In shapely 2.0.0 the following code produces an incorrect minimum_rotated_rectangle with area=20.4 when it should be 20.

In shapely <2.0.0 the correct minimum_rotated_rectangle with area=20 is found.

Steps to reproduce the problem.

"""
In shapely 2.0.0 the following code produces an incorrect
minimum_rotated_rectangle with area=20.4 and raises:

E        +  and   20.0 = <POLYGON ((1 1, 1 6, 5 6, 5 1, 1 1))>.area
