    Description

      If a cpp type is exposed to qml via qmlRegisterType,
      and this cpp type contains a signal `x` and a slot `onX`,
      when a `SignalSpy` qml element is connected to signal `x`, an error is thrown:

      `Error: Function.prototype.connect: this object is not a signal`

      This makes it impossible to have interchangeable cpp and qml types with the same API based on the x/onX idiom.

      example to reproduce:
