Description

During a reset Event, combobox does reset the selectedItem but doesn't respect the fact the current selectedItem might be included in the new source.

What I propose is to change

else if (ce.kind == CollectionEventKind.RESET)

{ collectionChanged = true; if (!selectedIndexChanged && !selectedItemChanged) selectedIndex = prompt ? -1 : 0; invalidateProperties(); }

to
else if (ce.kind == CollectionEventKind.RESET)

{ collectionChanged = true; if (!selectedIndexChanged && !selectedItemChanged && !collection.contains(selectedItem)) selectedIndex = prompt ? -1 : 0; invalidateProperties(); }
