The Virtual Keyboard "supports" InputMethod created with QML. It used to work when invokeMethod magically invoked the JavaScript over the C++ slot. However, it now crashes with a call stack exhaustion error when any of the following functions are called:

void InputMethod::reset()
{
    QMetaObject::invokeMethod(this, "reset");
}

void InputMethod::update()
{
    QMetaObject::invokeMethod(this, "update");
}

void InputMethod::clearInputMode()
{
    QMetaObject::invokeMethod(this, "clearInputMode");
}

 
It’s clear that this behavior has changed at some point.

What should be done with this API?

Note: The QML InputMethod is not actively used by the Virtual Keyboard itself.
