Reviewed by Dan Glastonbury and Kimmo Kinnunen.

Document::canvasChanged is only triggering a PrepareCanvasesForDisplay update if it is not given a rect.
WebGLRenderingContextBase::markContextChangedAndNotifyCanvasObserver was passing the whole canvas rect.
We change it to passing std::nullopt instead.
