Scaladoc should show protected members reached from search

[som-snytt]

Reproduction steps

Scala version: 2.13

Search occCounts in standard lib docs yields results that are not shown in the target page. It is protected[collection].

https://www.scala-lang.org/api/current/scala/collection/Seq.html?search=occCounts

https://www.scala-lang.org/api/current/scala/collection/AbstractIndexedSeqView.html#occCounts[B](sq:scala.collection.Seq[B]):scala.collection.mutable.Map[B,Int]

Problem

Search should only show results visible enable visibility of results in the docs.

Related issue for this case is #12083

ha, good catch

The Scaladoc feature is documented at scala/docs.scala-lang#1627 (comment)

As a bonus, occCounts has no doc comment.

Scaladoc 3 also has a widget to select protected members, but it doesn't show occCounts, which is qualified protected.

The additional bug axis, then, is only show unqualified protected members in the so-called public API.
