If we don't set the height property to -1 before requesting the preferred height, get_preferred_height() will just return us the fixed height that has been set before. We don't want this behavior here, so set the height to -1 before calling get_preferred_height(). This fixes a resizing issue where the keyboard is sized incorrectly after switching the monitor into portrait mode and back. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2306>
