The set_variation_by_name method of FreeTypeFont is inconsistent with the result #6439
Description
What did you do?
Traverse the font style of setting variation font.
What did you expect to happen?
The style changes every time you set it.
What actually happened?
The first one is visually the same as the second one. At the same time, the style obtained by getname() is inconsistent with the setting of set_variation_by_name().
variation_axes = [{'minimum': 300, 'default': 300, 'maximum': 700, 'name': b'Weight'}]
variation_names = [b'Light', b'Regular', b'Medium', b'SemiBold', b'Bold']
initial: ('Fira Code', 'Light')
set_variation_by_name: b'Light', get_name: ('Fira Code', 'Light')
set_variation_by_name: b'Regular', get_name: ('Fira Code', 'Light')
set_variation_by_name: b'Medium', get_name: ('Fira Code', 'Regular')
set_variation_by_name: b'SemiBold', get_name: ('Fira Code', 'Medium')
set_variation_by_name: b'Bold', get_name: ('Fira Code', 'SemiBold')
For comparison, I used Photoshop.
