    stylecontext: If we force invalidate, invalidate all properties
    
    We only FORCE_INVALIDATE when something weird changes that the CSS
    machinery can't detect. But now that our style_updated functions skip
    recomputations when some properties don't change we want to make sure
    these recomputations are still run. So we just claim all properties
    changed.
