Just to be sure, popups don't hit this code path, right?

Tests said it would not, but I looked at the code and have seen that it could
come there if it does not specify a target size (unlikely but not impossible). I
added therefore another special case here.

+       ash::Shell::IsForcedMaximizeMode())
+    *show_state = ui::SHOW_STATE_MAXIMIZED;
+
   ui::WindowShowState passed_show_state = *show_state;
   if (!GetSavedWindowBounds(bounds_in_screen, show_state))
     GetDefaultWindowBounds(bounds_in_screen);
