QStencilTestArguments::referenceValue takes no effect in RHI

It seems setting QStencilTestArguments::referenceValue to 1 takes no effect on rendering with RHI.

I add renderstates to the framegraph in the Basic shapes example to enable writing to the stencilbuffer.
I start the application in renderdoc.
With RHI, using QSG_RHI_BACKEND=opengl, nothing is written on the stencilbuffer, the corresponding function is also incorrect: glStencilFuncSeparate(GL_FRONT, GL_ALWAYS, 0, 0)
The 3. parameter is the reference value that’s supposed to be set via QStencilTestArguments::setReferenceValue in the qt3d framework.
Running the same application with QT3D_RENDERER=opengl, it produces the expected result (loading it in renderdoc, I can see values on the stencilbuffer and I can see the corresponding function correctly set: glStencilFuncSeparate(GL_FRONT, GL_ALWAYS, 1, 0)).

Changes to main.cpp in basic shapes (skipping the necessary includes here):

 //FrameGraph
 

{      auto renderStates = new Qt3DRender::QRenderStateSet();      auto* stencilTest = new Qt3DRender::QStencilTest();      stencilTest->setEnabled(true);      stencilTest->front()->setReferenceValue(1);      stencilTest->front()->setStencilFunction(Qt3DRender::QStencilTestArguments::Always);      auto* stencilOp = new Qt3DRender::QStencilOperation();      stencilOp->setEnabled(true);      stencilOp->front()->setAllTestsPassOperation(Qt3DRender::QStencilOperationArguments::Replace);      stencilOp->front()->setStencilTestFailureOperation(Qt3DRender::QStencilOperationArguments::Keep);      stencilOp->front()->setDepthTestFailureOperation(Qt3DRender::QStencilOperationArguments::Keep);      auto* stencilMask = new Qt3DRender::QStencilMask();      stencilMask->setEnabled(true);      stencilMask->setFrontOutputMask(0xFF);      renderStates->addRenderState(stencilTest);      renderStates->addRenderState(stencilOp);      renderStates->addRenderState(stencilMask);      view->activeFrameGraph()->setParent(renderStates);      view->setActiveFrameGraph(renderStates);  }
