regression after 96a4d95

Looks like we can't actually use $stable here. I assumed slots used an effect to track dependencies but they actually only render if the parent does, so a slot referencing variables other than from its arguments isn't "stable". In this case it's

vuetify/packages/vuetify/src/components/VTreeview/VTreeviewChildren.tsx

Line 212 in 96a4d95

items={ children }

but the same thing happens with other props like indentLines
