	* gtk/gtktextdisplay.c (render_layout_line): handle NULL shaped
	object from the empty-child-anchor case by drawing a little box.

	* gtk/gtktextlayout.c (add_child_attrs): Still set shape attribute
	if the child anchor has no anchored widgets - fixes #59328.

	Also, remove bizarre deletion of preedit string that seems to have
	gotten in here somehow.
