I think the current behavior with the empty list item is correct, 
actually. Other browsers don't show the list item (and renumber the list 
as appropriate) because the CSS rule for ".mw-empty-elt" has "display: 
none". EWW/SHR don't parse CSS[1], and so we show the empty item.

You can see the same "problem" in Firefox if you load 
<https://en.wiktionary.org/wiki/locus#Noun> and go to View -> Page Style 
-> No Style. Since that's roughly what EWW/SHR is doing, I think we're 
consistent with other browsers here.

[1] Well, they can parse some limited inline CSS using the "style" 
attribute, but that doesn't apply here since the styling comes from a 
CSS class.
