+// The FindBarHost implements the container widget for the
+// find-in-page functionality. It uses the appropriate implementation from
+// find_bar_host_win.cc or find_bar_host_gtk.cc to draw its content and is
+// responsible for showing, hiding, closing, and moving the widget if needed,
+// for example if the widget is obscuring the selection results. It also
+// receives notifications about the search results and communicates that to
+// the view.
+//
+// There is one FindBarHost per BrowserView, and its state is updated
+// whenever the selected Tab is changed. The FindBarHost is created when
+// the BrowserView is attached to the frame's Widget for the first time.
