Width handles keep the point the text is aligned on

Which point of a symbol's text stays in place while its width is
dragged now follows the text's alignment, the nine points of its
alignment dialog, rather than the handle: a text aligned top right
keeps its top right corner whichever handle is dragged, one centred
keeps its middle, and a text that wraps grows away from that point.
