QSS QComboBox QAbstractItemView exapand by sizePolicy

[brcontainer]

I'm trying to make pop-ups work the combobox without textElide and sizePolicy exapand (I'm using QSS)


QComboBox QAbstractItemView {
qproperty-textElideMode: ElideNone;
}

QComboBox QListView, QComboBox::item{
qproperty-vertSizePolicy: Expanding;
}

but does not work, items from the QComboBox does not expand the size of the pop-up.

How to make pop-ups expand the size without affecting the combobox?
