Suffix not capitalized when all upper case

What steps will reproduce the problem?

1. from nameparser import HumanName
2. k = HumanName("WOOT ALFRED DOUGHERTY III")
3. k.capitalize()

What is the expected output? What do you see instead?
Expected :

<HumanName : [
        Title: '' 
        First: 'Woot' 
        Middle: 'Alfred' 
        Last: 'Dougherty' 
        Suffix: 'III'
]>

Output that I see instead :

<HumanName : [
        Title: '' 
        First: 'Woot' 
        Middle: 'Alfred' 
        Last: 'Dougherty' 
        Suffix: 'Iii'
]>

This seemed to work.

>>> k = HumanName(("WOOT ALFRED DOUGHERTY III").lower())
>>> k.capitalize()
>>> k
<HumanName : [
        Title: '' 
        First: 'Woot' 
        Middle: 'Alfred' 
        Last: 'Dougherty' 
        Suffix: 'III'
]>
