[REG 5.11.3->5.12.0] QML parsing error

QML parsing error for a property with JS object literal ending with semicolon.

// Sample.qml
import QtQml 2.0

QtObject {
    property var field: { "key": "value"};
}

The error "Unexpected token `;'" in case of runtime and compile-time generation (add in .pro file CONFIG += qtquickcompiler)  "Error compiling qml file: [...]: error: Unexpected token `;'" .
