      QJSEngine::evaluate changed behaviour from 5.10 to 5.11 for strict mode scripts:

          QJSValue def = engine.evaluate("'use strict'; function foo() { return 42 }");
    QJSValue globalObject = engine.globalObject();
    QJSValue foo = globalObject.property("foo");

    QJSValue use = engine.evaluate("'use strict'; foo()");

      Here foo was a function object in 5.10, but is undefined in 5.11. So use will be ReferenceError in 5.11, while it did work in 5.10.
