    Remove composer's scrolled window since WebView now scrolls internally.
    
    We can't easily wrap ComposerWebView in a GtkScrolledWindow, since we
    don't any notifications that the cursor has moved offscreen and hence the
    view needs to be scrolled, so let the view do its own scrolling.
    
    * ui/composer-widget.ui: Replace editor_scrolled with editor_container,
      update uses.
