+From c73968d63c456d4aaf55c5cd439b42403a3bbeb1 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Fix browser frame view not getting a relayout after a state change
+
+views::NonClientView has 2 things: a views::NonClientFrameView and a
+views::ClientView. We were previously only invalidating the layout on
+the ClientView after a state change.  This was causing the browser
+frame to paint as if it were still maximized after restoring from
+a maximized state on Linux.  Invalidating the layout of the frame view
+fixes the issue.
