[csswg-drafts] [css-inline-3] Behavior of initial letter property with 1st argument value set to [0, 1)

chenpighead has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-inline-3] Behavior of initial letter property with 1st 
argument value set to [0,1) ==
Per https://drafts.csswg.org/css-inline/#sizing-drop-initials, it says
 the first argument (size of a initial letter) accepts non-negative 
<number>. If I read correctly, it means setting initial-letter with 
size [0, 1) is allowed. However, I wonder: (1) what is the use case 
for setting initial-letter's size to less than 1? (2) what is the 
expected behavior for setting initial-letter's size to 0?

Would it be better to specify that the first argument should be 
"larger or equal to 1"?
