SortGroup Events

update:sorted

Emitted when the active sort array changes. Reset sort emits an empty array, which the host reads as "use the default" rather than as "sort by nothing" — a list with no o param is one the server sorts by its own default anyway. useViewList answers it by clearing the stored sort preference and applying defaultSorted; a host that just assigns what it receives clears the sort instead. Emitting defaultSorted here would say the opposite: useViewList would store it as an explicit preference, which is the one thing a default is not.
