// This test originally expected bookmarks added after visits to boost frecency
// scores. The frecency algorithm has since changed - adding a bookmark after a
// visit doesn't retroactively change the frecency score for a site unless no
// visits exist for a bookmark.
//
// This test now verifies that frecency remains stable when bookmarks are added
// and removed after visits, and ensures eraseEverything() doesn't modify the
// frecency calculation.
