QtQuickCompiler: When using singletons and loaders then more than one instance of the singleton may be created

QtQuickCompiler: When using singletons and loaders then more than one instance of the singleton may be created. With the attached example, if qtquickcompiler is enabled then it will indicate that the two objects (which should be the same) are actually different. When it is not enabled then the two objects are the same. This can be checked via the output as it should say:

true true

but it currently outputs

true false
