Smart cropping sometimes has the wrong dimensions

[ataylor32]

This is what I'm running (the image is from here):

from sorl.thumbnail.shortcuts import get_thumbnail
thumbnail = get_thumbnail(
    'https://upload.wikimedia.org/wikipedia/commons/0/09/Closing_panel_of_PyCon_Asia_Pacific%2C_Ngee_Ann_Kongsi_Auditorium%2C_Singapore_Management_University_-_20100611.jpg',
    '200x200',
    crop='smart',
)
print(thumbnail.size)

This is the output:

[30, 200]

This is what I would expect the output to be:

[200, 200]

This is what I have installed:

Django==3.1
Pillow==7.2.0
sorl-thumbnail==12.6.3
