Child position on in span of parent position for enum constant with bodies

Consider code like:
---
public enum E {
   A {
        int i;
    }
}
---

This is desugared in parser using anonymous class definition. But the span for the NewClassTree does not fully enclose the span of the embedded ClassTree - the NewClassTree begins at '{', but the embedded ClassTree beging at 'A'. A testcase is attached.
