Scrolling locks once scrolled upwards
On mobile devices, if one scrolls down (moving the finger upwards) in a chat page, scrolling doesn't work anymore, i.e. the message list freezes.
It could be related to the following warnings:
Could not attach Keys property to: Action_QMLTYPE_63(0x55dcfdfc8830) is not an Item file:///home/user/kde/usr/lib/x86_64-linux-gnu/qml/org/kde/kirigami.2/templates/private/ScrollView.qml:95:5: QML QQuickItem: ScrollBar must be attached to a Flickable or ScrollView
The error and the related warnings only appear when
QT_QUICK_CONTROLS_MOBILE = true is set (and therefore the scroll bar is missing), otherwise not.
