Redo the way that the summary item expand/collapse animation works so that the items all resize in unison so that when moving from one to another, the summary area as a whole stays a constant width rather than wobbling slightly. (Also rename all references to the "minimum" summary item title width, since it's not a minimum, it's just the width.) https://bugzilla.gnome.org/show_bug.cgi?id=630546
