QJSEngine variables in Locals window while debugging

[Tarae]

I have a simple program:

#include <QCoreApplication>
#include <QJSEngine>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QJSEngine engine;
    engine.evaluate("var foo = 3;");
    //breakpoint
    return a.exec();
}

When I run debugging and step to breakpoint, my locals window looks like this:

Is there a way, how can I see variables in js engine in this window too? Or in other window?
I've read QML Debugger Console can evaluate JavaScript expressions, so I tried:

But it does nothing.
