User story:

As VE user I want to be able to correctly see and save sub-refs if the main content is duplicate among sub-refs.

Acceptance criteria:

<ref name="abc" details="p. 123">ghi</ref>
<ref name="abc" details="p. 456">ghi</ref>

• Shows two sub refs [1.1] and [1.2].
• Sub-refs can be edited individually in VE.
• When changing details in VE they update on save in Wikitext. The main body stays the same,

Out of scope:

• Unnamed main ref
• Editing the main content. This is broken behavior in VE already when duplicate main content is used with the same name.
