Yikes, can reproduce with Qt 5.12.3... but not with 5.12.0. This points to it being a Qt regression, urgh. Can you please report it to them? Then please paste the URL of the Qt bug report into a comment in this ticket. Thanks!
Well, I'm having the same issue, I reported it to QT now: https://bugreports.qt.io/browse/QTBUG-75900
