Strange behavior with QuickFlux 1.1 and Qt 5.13.0

[CaseySanchez]

Build kit: Qt 5.13.0 MSVC2017-64 Project: test.zip

Hello, in the test project that I have attached I have encountered some weird behavior.

1. Store/Filter combo does not seem to work, as a result I've used Item/AppListener in my singleton UserStore.
2. My singleton UserStore does not receive dispatched actions until an operation is done on the singleton (I'm not sure if this means that it isn't instantiated until this point or if flux is having an issue connecting the signals).

For example, in main.qml I have a no-op line of UserStore; that allows the actions to flow properly, where if it is removed the actions no longer flow.

The tree is simple:

main.qml
actions/
    ActionTypes.qml
    AppActions.qml
    qmldir
stores/
    UserStore.qml
    qmldir

UserStore.qml:

pragma Singleton

import QtQuick 2.12
import QuickFlux 1.1

import "../actions"

// This does not work

/*Store
{
    Filter
    {
        type: ActionTypes.login

        onDispatched:
        {
            console.log("dispatched");
        }
    }
}*/

// This does work

Item
{
    AppListener
    {
        filter: ActionTypes.login

        onDispatched:
        {
            console.log("dispatched");
        }
    }
}

main.qml:

import QtQuick 2.12
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.5
import QtQuick.Controls.Styles 1.4
import QtQuick.Window 2.3
import QuickFlux 1.1

import "actions"
import "stores"

ApplicationWindow
{
    id: appWindow

    visible: true
    width: 640
    height: 480

    Button
    {
        anchors.fill: parent

        font.pointSize: 20
        text: "Login"

        onClicked:
        {
            AppActions.login();
        }
    }

    Component.onCompleted:
    {
        UserStore; // The action in "Button.onClicked" is no longer received if this no-op line is removed.
    }
}

EDIT1: Issue #2 persists even when QuickFlux is removed entirely and replaced with a simple signal/slot mechanism, so it appears to be related to how the singleton object is instantiated in QML.

EDIT2: The profiler confirmed these findings, UserStore is only created when the no-op call is made. Could anyone else confirm this please?
