I've found the problem of this failure.

When QtWebPageSGNode destructed, CoordinatedGraphicsScene clears its all of resources including m_registeredLayers during purgeGLResources but CoordinatedLayerTreeHost clears just backingstores.

To fix this failure, I think we need to destruct all of CoordinatedGraphicsLayers in CoordinatedLayerTreeHost during purgeBackingStore.
