Shouldn't allow using bidiSpanWrap in content kind "text"

I found when I accidentally used the `bidiSpanWrap` directive in a template block with `kind="text"` it would look fine in simple cases with same text directionality but show literal ``s in the content in other cases. Since this directive is fundamentally incompatible with `kind="text"`, is it possible for the compiler to detect this incompatible usage and give an error?
