    Revert "Add a release note for scrolled windows"
    
    This reverts commit 76af90767634f5caea622c2abc13d21adb41550c.
    
    The behavioral change described in the migration guide
    has now been made optional with new scrolled window API,
    so no need to mention this in the migration guide.

-      GtkScrolledWindow now respects the natural size of its child and passes

-      size of the scrolled window.

       GtkHeaderBar now respects the hexpand property for its custom title

       layout of those children to change, if they unintentionally had hexpand
