I’m using PySide6 and see a vertical blue line next to QComboBox items when hovering over them. I want to remove or customize them.

                combobox_style = """
        QComboBox {
            color: white;
            background-color: #4F4F4F;
            font-size: 16px;
            border-top-left-radius: 10px;
            border-top-right-radius: 10px;
            border-bottom-left-radius: 10px;
            border-bottom-right-radius: 10px;
            font-weight: bold;
            padding: 5px;
        }
        QComboBox:on {
            border-bottom-left-radius: 0px;
            border-bottom-right-radius: 0px;
        }
        QComboBox::drop-down {
            width: 20px;
            border-left-width: 0px;
            border-top-right-radius: 10px;
        }
        QComboBox::down-arrow {
            image: url(./Pictures/60995.png);
            width: 12px;
            height: 12px;
        }
        QComboBox QAbstractItemView {
            color: white;
            background-color: #4F4F4F;
            selection-background-color: #666666;
            border-bottom-left-radius: 10px;
            border-bottom-right-radius: 10px;
        }
        QComboBox::item {
            padding: 4px;
        }
        """

This is what I am expecting it to look like:

The blue line would be orange when hovering over the items and the backround would be orange when an item is selected.

Any help would be greatly appreciated.
