Cannot set folder in FileDialog from QtQuick.Dialogs 1.0

[gaess]

I don't know if it's a bug or if I'm doing anything wrong.
No matter what value I assign the folder property to, the fileDialog always shows the application source folder.
I've tried different values: "file:///home", "file:///home/", "~", shortcuts.home, Qt.resolvedUrl("/home")
None of them had any effect. I'm on Debian 10.3, Qt 5.14.0
Here's my code:

import QtQuick 2.2
import QtQuick.Dialogs 1.0
FileDialog {
    id: openFileDialog
    title: "test"
    folder: "file:///home"
}

Is this working for you? Do I need to change anything?.
