EDIT: there are many places I found vocal SHEVA treated as silent SHEVA.
E.g. Gen. 10:11 אֶת־נִ֣ינְוֵ֔ה
ʔɛθ-ˈniːinˈveː
ˈniːinˈveː should be ˌniːnaˈveː

This issue is upstream in the havarotjs package, tracked here
That one may take some substantial work, and will likely have some trickle down effects (api shape will likely change -> so schemas have to change -> so the site has to change)
