The height of ComboBox can be incorrect, for example on Android with Fusion style ComboBox height is not enough for `g` symbol, see attachment (qt6_combo).

There is no customizations with the ComboBox in my app, it is declared as follows:

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts

Page {
...
            ComboBox {
                id: levelComboBox
                Layout.fillWidth: true
                currentIndex: 1
                model: scene.levelNames
                onCurrentIndexChanged: {
                }
            }
...
}

On Windows it looks even worse, see combobox.png, but with default style it looks ok, see combobox1.png.

I published this on the forum first and did not receive an answer explaining this behaviour.
