Too many services on list when accessing services property multiple times in declarative ServiceList component

Using ServiceList declarative element every time one refers to its services property, new services are added.
Here is some code snippet:

var lst = myServiceList.services.length;
console.log(lst);
lst = myServiceList.services.length;
console.log(lst);
lst = myServiceList.services.length;
console.log(lst);

Output here is depending on servcies count, so eg.: 3, 6, 9 as list has the same entries added every time property is accessed for READ.
At first glance fix is as easy as clearing internal member list before adding any new services::
