    Bug 1774815 - Make sure if layers connection is requested by parent r=jnicol,gfx-reviewers,bradwerth a=pascalc
    
    We want to skip InitRendering only when parent side does not requested to connect layers. Current implementation is not clear about meaning of "mLayersConnected == Some(false)". It has the following 2 meanings.
    [1] parent side does not request to connect layers.
    [2] parent side requested to connect layers, but the connect was failed.
    
    We need to distinguish between [1] and [2]. mLayersConnectRequested is added for it.
