Right Mouse Button is not detected

[lonelyteapot]

Below is QML code containing a MouseArea and some Texts that show if LeftButton and/or RightButton are pressed.

On Desktop, everything works as expected. But when compiled for WebAssembly, only LeftButton press is registered.
RightButton is not detected, even if Left is also pressed down. MiddleButton doesn't seem to work as well.

Tested on Firefox and Chrome.
The project is built using QtCreator with generated by default main.cpp and CMakeLists.txt.
Versions used: Qt 6.2.1, Emscripten 2.0.14.

import QtQuick
import QtQuick.Window

Window {
    width: 640
    height: 480
    visible: true

    MouseArea {
        anchors.fill: parent
        acceptedButtons: Qt.AllButtons

        Text {
            id: text_left
            anchors.centerIn: parent
            font.pixelSize: 28
            text: "Left button: " + ((parent.pressedButtons & Qt.LeftButton) ? "pressed" : "not pressed")
        }

        Text {
            id: text_right
            anchors.top: text_left.bottom
            anchors.horizontalCenter: parent.horizontalCenter
            font.pixelSize: 28
            text: "Right button: " + ((parent.pressedButtons & Qt.RightButton) ? "pressed" : "not pressed")
        }
    }
}

+1 for this issue, a real show-stopper for our project.
