    Description

      Suppose an object is created in C++ and its ownership is set to CppOwnership explicitly by QJSEngine::setObjectOwnership(). 

      Once it is referenced by a list element and its invocable method is called by QML engine, then its ownership turns to JavaScriptOwnership.

      I made an autotest that reproduces the issue.
