	* gtk/gtktextview.c (popup_targets_received): only sensitize Cut
	if selection contains some editable text, #60975
	(gtk_text_view_scroll_to_iter): remove warning about scrolling
	prior to map; it should actually be OK to do so in many cases,
	it would be nice to warn about scrolling when many lines have
	height 0, but I don't know what to do about that. Perhaps
	move part of flush_scroll into this function? comment added
	to consider this.
