Qt.createQmlObject filepath parameter does more than documented

In documentation of createQmlObject:

If filepath is specified, it will be used for error reporting for the created object.

http://doc.qt.io/qt-5/qml-qtqml-qt.html#createQmlObject-method

Additionally, if this path is file url (such as file:///path/to/somewhere), it will also be used as a search directory for relative files referenced in created QML object. For example:

Qt.createQmlObject('import QtQuick 2.4; Image{ source:"file.png" }', parent, "file:///tmp/something.qml")

This will search file.png from /tmp.

Either this feature should be removed (and search should be relative to file where this new object was created) or this should be added to documentation.

In case this is staying, should http scheme (and others) also be supported? Now only file seems to be working this way.
