What is the current behavior?

When using ViewEngine, insertBefore is always called with the result of nextSibling. On Ivy this has changed so the View itself is returned. The current implementation will ignore view order when running with ivy

What is the new behavior?

Support view references to be passed to insertBefore, fixing positioning issues.

Fixes #2176 #2249.
