qt_generate_deploy_qml_app_script cannot deploy for native FolderDialog

My project uses qt_generate_deploy_qml_app_script to create a deployment of the program.

Before running the deploy script, the program can invoke a native FolderDialog on Ubuntu's default desktop.

After running the deploy script, the deployed version of the program cannot invoke a native FolderDialog, but can only invoke a very primitive and malfunctioning FolderDialog.

I guess the deployment script does not collect enough stuff for native FolderDialog. Instead, a fallback version is invoked, which is malfunctioning.

 The FolderDialog used is this:
