ListView with asynchronous Loader delegate crashes when changing indexes

Crashes when switching a ListView currentIndex many times for a Loader delegate with asynchronous=true.
Quick fix seems to be setting active=false in Component.onDestruction of Loader.
May have something to do with async load coming back for item which no longer exists.

Attached test project.
Can simulate either using qmltestrunner, or qmlscene and clicking the view.
