    Description

      This fails in dev:

      QString null;
QVERIFY(null.isNull());         // OK
QStringRef nullRef(&null);
QVERIFY(nullRef.isNull());      // OK
QStringView nullView = nullRef;
QVERIFY(nullView.isNull());     // FAIL

      Expectation is that, like in Qt 5, nullness is preserved.
