Thomas Lübking 7efc42774f delay withdraw of support props
The CM selecton withdraw delay was introduced to mostly unburden
plasma from recreating the theme on temporary changes, but since
plasma also watches some properties hinting supported features
and acts in consequence, this isn't sufficient and actually causes
two theme changes instead of one in the case of a regular suspend
