Unsolved font properties overriden

[ebatsin]

Hi!

I have a custom Text component that I use for all the texts in my application :

import QtQuick 2.12
import MyTheme 1.0

Text {
    font: Theme.fonts.defaultFont
    color: Theme.colors.defaultTextColor
    renderType: OsInfo.isWindow ? Text.NativeRendering : Text.QtRendering
}

Theme.fonts.defaultFont is defined as follow:

property font defaultFont: Qt.font({
    bold: false,
    family: myFont.name, // a font loaded somewhere else in the file
    pointSize: 10
})

I am requesting a specific font family, but if I do the following :

MyCustomText {
    text: `Some text`
    font.pointSize: 15
}

The font properties are reverted (the font family defined in MyCustomText seems to go back to the default value with a point size of 15. If I do not modify the font's point size, the right font family is used

Any idea on what causes this and if there is a workaround ?

Thanks
