QUrls passed from C++ to QML seem to be compared by reference instead of value

Comparing urls in QML when assigned to a property:

property url myUrl0: "http:///blabla"
property url myUrl1: "http:///blabla" 

like so:

root.myUrl0 === root.myUrl1 

would evaluate as "true" (=> comparison by value?)

When a QUrl is passed from C++ to QML, it should be automatically converted into a url but those urls have very different behavior in comparisons. They look more like they are being compared by reference since almost any other comparison than "url_passed_from_cpp === url_passed_from_cpp" evaluates to false.

Steps to reproduce the issue:

1. Run the attached project
2. Click "push to emit"
3. observe application output
