palabras(menubar): Enter en el popover de escape confirma y cierra

El campo confirmaba en vivo (oninput) pero Enter no cerraba el popover. Handler
onkeydown: Enter (no en textarea) hace blur (vuelca los que confirman en change:
number/length/select) + cierra. Textarea conserva Enter para salto de linea;
Esc / clic fuera tambien cierran. Verificado en Chrome real (Enlace: escribir +
Enter -> cierra con el valor puesto).
