For _TextBoxMixin too, monitor touchend in addition to mouseup. Also, use this.own() with dojo/on instead of deprecated this.connect() . Refs #16622, #16585 !strict.

For _TemplatedMixin, use this.own() with dojo/on instead of deprecated this.connect() (which uses the deprecated dojo.connect()).   Perhaps in the future we should setup a more standard way to map from strings to synthetic events, for example data-dojo-attach-event="dojo/mouse.enter: _onMouseEnter" instead of data-dojo-attach-event="mouseenter: _onMouseEnter".   Refs #16585 !strict.
