Interpolation is broken on root nodes

A component with
`@View(template: `<other-cmp>{{text}}</other-cmp>`})` does not interpolate text correcty (if fact it doesn't even throw).

However, 
`@View(template: `<other-cmp><div>{{text}}</div></other-cmp>`})` works, which points to some indices being wrong. It is possible this is related to inserting shimmed CSS and breaking the element counts.
