When resolving a reference like paragraph (i) and we happen to be in PARA (i), don't link to ourselves

It's highly likely to be wrong.

This is complicated. We have to first find the closest (semi-) hierarchical element that contains the citing text, and then exclude that, but only if there are no child references.

For example, if we're in section 1, we don't want to ignore section 1 in the reference section 1(a).

We also don't want to get confused in this case: if we're in section 2 > subsection (i) > para (a) > subpara (i) we don't want to ignore subsection (i) because we're inside subpara (i).
