Sending key event through sendEvent from QObject event filter ignores QML Shortcut

When sending key event through sendEvent, the event is ignored by Shortcut in QML.
It seems the same problem as QTBUG-48325 but this is in QML. 

 How to reproduce:
1. Run attached sample code
2. Press "A" key

 
Expected output:
receive Key event code=0x00000041
receive Key event code=0x00000042
qml: B received
qml: onPressed: key=42
qml: onPressed: key=41

Actual output:
receive Key event code=0x00000041
receive Key event code=0x00000042
qml: onPressed: key=42
qml: onPressed: key=41
