    Description

      In both Qt 5 and 6 instanceof operator doesn't work in cases like in the example:

       

      import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    width: 640
    height: 480
    visible: true

    Text {
        text: "result: " + (loader.item instanceof MyButton)
    }

    Loader {
        id: loader
        source: "MyButton.qml#2"
    }
}

       

      This behavior is especially problematic for hot reloading, where fragment part helps trick the cache and force the component to be reloaded from source.
