// of tab_groups::TabGroupIds and TabGroups and provides an API for maintaining
// it. It is owned and used primarily by TabStripModel, which handles
// tab-to-group correspondences and any groupedness state changes on tabs.
// TabStipModel then notifies TabStrip of any groupedness state changes that
// need to be reflected in the view.
