I can reproduce this one fairly frequently when I repeatedly search for things, click on them, and start a new search.
Also QQuickItemPrivate::deliverKeyEvent(), just like Bug 378339. Shall we mark it as a duplicate?
Yup. This is caused by a Qt bug: https://bugreports.qt.io/browse/QTBUG-65881, which should be resolved by https://codereview.qt-project.org/#/c/217395, once that lands.
