Rollup merge of rust-lang#149026 - GuillaumeGomez:test-for-reexported-variant, r=lolbinarycat

Add test for href of reexported enum variant

Working on rust-lang#148648 and realized that we actually didn't test for enum variants reexports, so here we are.

I also think I'll do rust-lang#148648 at the same time as rust-lang#148547.
