QML: When using the Material style's ComboBox and filling the model with so many items that the ListView of the Popup becomes scrollable, Qt warns about null objects:
WARN Qt default - file:///C:/Qt/5.15.0/msvc2019_64/qml/QtQuick/Controls.2/Material/ComboBox.qml:68: TypeError: Cannot read property 'Material' of null
WARN Qt default - file:///C:/Qt/5.15.0/msvc2019_64/qml/QtQuick/Controls.2/Material/ComboBox.qml:66: TypeError: Cannot read property 'width' of null
Qt Support has tested this with Qt 5.15 and get same errors.
Example project attached.
