A type with :nodoc: can still be documented #16718
Description
As soon as the doc for any (re)definition of a type declares :nodoc: the type should never be documented, but as demonstrated in #16714 a type with multiple :nodoc: can end up being documented!
A comment on the thread_local macro call happened to become the doc comment for Thread, regardless of all the :nodoc: comments explicitly set to the type at different other places.
Maybe it happened to become the first doc comment for Thread, then it was reopened and their doc comments got skipped, hence skipping :nodoc:?
