notifyComponentsOnChangedSelection was added in a very old WebKit merge in the downstream repository when we added alternative text controller in WebKit to respondToSelectionChange. The person who merged WebKit change probably didn't realize this but things in respondToSelectionChange should really be moved into notifyComponentsOnChangedSelection and vice versa so simply merge them together.
