QML "file://" Import not working

I have an application, where:
*QML Files are in resource file
*main.qml
*RedRect.qml
*QML Files are in relative directory
*GreenRect.qml
*qmldir

When trying to import the relative directory inside main.qml following happens:
1. Directory import succeeds
2. qmldir file is resolved correctly and recognized that GreenRecti Item refers to GreenRect.qml
3. I get an error that GreenRect.qml file is not found, even though it is in the same folder as qmldir and relative to the imported directory.

This issue is easily resolved by providing absolute path with "file:///", which proves that there is a bug at some point in the process of loading of the QML item.

Full console log:

QML debugging is enabled. Only use this in a safe environment.
qrc:/qml/main.qml:11:5: Type GreenRecti unavailable
file://qml/MixedResource/GreenRect.qml: File not found

I have attached a really small and simple example that reproduces the problem easily
